Rolltop Waterproof Backpack

by:Max Apparel     2020-08-30
How hard is it to make a backpack?
Just a big rectangle with some straps and other pockets, right?
But when you\'re looking for a backpack, it\'s somehow impossible to find a backpack that\'s completely waterproof, clearly visible, easy to see and just the size you want.
So this is a backpack I made, completely waterproof, about $30.
You can spend more money on materials, and you can spend less!
I bought all the nylon straps and buckles for the teal backpack--
It cost me $3 and I found an old TV suitcase of 3 yards 1.
5 inch nylon, 2 triglides and 6 buckles, only some seams are required to tear.
I spent less money on flower backpacks-
The price of the curtains is $2. 50, belts $0. 50 each (
Five belts per backpack). Materials: -1-
2 yards of backpack exterior fabric (
I found cordua at my fabric store for $5/yard, but look at the thrift store for large windbreaker, curtains ---
You want something with a lot of thickness and weight)-
1 \"about 3 yards of nylon-
With your 1 \"nylon (
If you use thicker nylon, use thicker triglides)-
2 buckles, with your 1 \"nylon-
1/2 thick foam (
Filling of back and bottom)-
Waterproof fabric lining (I used tarps--
10 \'x12\' a piece of fabric is $10, but you can use shower curtain, laminated cotton as you like.
You can also use
If you don\'t want a waterproof backpack, waterproof fabric like a roll top.
Or you can make a different top!
But you might want a different structure. )-seam sealer (
Be sure to use the sewing machine.
Don\'t just stick tape to the edge of the lining.
I don\'t approve of this at all because it\'s cheap, functional waterproof and very low
You spend a lot of energy on the budget of this backpack.
Just kidding, I completely sealed the edge of the lining with tape, which is cheap & Waterproof & perfectly usable on things that don\'t touch the skin at all. )optional: -
Reflective fabric (
I managed to get some reflective vinyl from my mom and she put it there)-
1 \"thick foam, use a heavier 2\" cotton belt if you want to make a padded belt, or if you don\'t want (
Also easy to be frugal in the form of belts)-
Mesh fabric for side pockets I have drawn all the patterns I use in the picture above.
I highly recommend that you put these things on the newspaper, on the plastic sheet, or just on the print paper that is attached together, as you will use them multiple times.
The longest part of the process is to come up with this pattern!
Please feel free to adjust your backpack--
This backpack is perfect for a 17-inch computer and you may want to reduce the size if you are planning to bring less.
It is also important to get a good pattern in your mind before you make this pattern, so here is: this is a rolling backpack.
Each of your clothes will be 25 \"high: 17\", of which 25 \"high\" will be the main body of the backpack and the rest of the 8 inch will scroll down.
The top of the roll is fixed by two buckles, as shown in the figure, which are attached to the front and back of the bag, right where the straps come out.
When you make these backpacks, it is important to do all the small details first.
Plan your pocket.
Where do you plan to add D-
Rings, used to connect your keys, where you want to add reflective stripes, are more visible on the bike at night, if you want an extra strap to connect the flash of the bike, or if you want to install nylon on the side of your backpack.
How many pockets do you want?
Do you want a pocket on the side?
Do you want a water bottle pocket?
Feel free to use the patterns I see here, but I also encourage you to branch out!
You just sew a rectangle with some shoulder straps that scroll down at the top and you should put whatever crazy thing you want on top.
Do you want to embroider the flower on the front flap?
Please send me the picture
Do you want to cover it with sequins or peacock feathers?
Yes, I want you to do the same!
If you think that the front and sides of the backpack have elastic bands that will allow you to carry the most flexible things, then sew the elastic bands on it!
If you are buying a new fabric, if you are using the brandnew never-before-
Used nylon, great!
You can skip this step.
Otherwise, welcome to my favorite step! Get comfy.
This is very time consuming.
First of all, the reason I want to make a backpack is because of this blue trench coat above. Yes, that one.
I have been wearing this trench coat for ten years and I like it very much.
Did I go through, you ask?
The answer is a resounding no.
When I saw this trench coat at Burlington Coat Factory at the age of fourteen, I fell in love with the color (
So strong blue doesn\'t even show up in this photo).
The petite fact of the 14 th did not prevent me from forcing my mother to buy it for me for $30.
Although I have a lot of things, I am not and will never be the petite size of size 14, so I can count the number of times I wear this coat with one hand. (
It has now been taken apart, the seams are taken apart, waiting to be a backpack. )
It would be great if you made a backpack with a trench coat!
Windbreaker is usually made of four or five yards of fabric, usually made of stronger fabric and worse weather
Waterproof fabric is perfect for backpacking.
However, you will spend a lot of time preparing.
Get an open hand and get familiar with it, because you will spend a lot of time tearing off all the seams of this trench coat and tearing them into five or six pieces (
Two rear, two front, two arms and padding).
The biggest benefit of using windbreaker is that you can add a lot of really cool stuff to your last backpack ---
Epaulettes become useful compression bands on the side!
The front trench coat pocket can be a secret pocket sewn in the side seam!
There are so many buttons!
If you don\'t want to have a fully waterproof lining like the rest of this instructable, the lining becomes a very cute lining for the backpack itself.
As for the other fabrics that are saved, it\'s crazy!
Find some interesting curtains, or some regular ones that you think will look good like a backpack (
See the green curtains of my gold and crimson embroidered flowers, which turns into two beautiful backpacks).
Use a duvet, coat (
Anyone? ), wool suits (
Fashion wool backpack from Hella?
Old leather jacket (
But be careful to sew leather unless you know your sewing machine can handle it).
I like to look at coats and suits in thrift stores. -two often-
The neglected part has a gold mine of fabric choice, usually a natural fiber of high quality.
When you look through all the neglected suits, it\'s much easier to find wool, silk and linen than you think!
Also don\'t forget to look for other materials in thrift stores.
The price of buying neigon is from $1-$3 a yard;
By contrast, ugly luggage bags with yards and yards of nylon are only $3 in goodwill.
Looking for big luggage with lots of nylon, lots of buckles and lots of triglide regulators.
If the bonus points are torn, it doesn\'t work anyway!
I got all my nylon and buckle from a strange molded plastic that was designed to hold a 90-inch TV. Goldmine.
Don\'t be afraid to branch out--
The flower backpack does not use nylon straps at all, but the straps themselves, the straps between the straps and the bags, and the straps that close the top of the roll are woven canvas belts, which are easy to find in every thrift store, there are a wide variety of widths and lengths, each with its own closing mechanism.
Don\'t like plastic safety-
Vest style buckle?
Find a belt with a stylish buckle and add some vintage charm to your backpack.
The beauty of making a backpack is that you can make a backpack with whatever you want.
Make a Chevron backpack, make a flower curtain backpack, make a duck backpack, make a thin striped suit backpack, and make a quilting backpack!
I just wish I could restrain myself because now I want to make backpacks with every slightly fun pattern I see at the thrift store.
Assemble the outside of the backpack.
Cut off your front and back, your bottom, your two sides.
I found 17 \", this is 25\" long marked on these fragments. -
In this way, you know which 17 are the main body of the backpack, and you also know that the rest of the backpack is rolled to the top.
Don\'t sew them together.
Assemble the front!
Cut your pocket.
My pattern includes two front pockets with flaps: feel free to change and make a backpack with a wide front pocket with three layered pockets sewn on it, no pockets, there are only elastic bands sewn on the front.
After you sew your favorite pocket, sew the two 4 \"long nylon and attach the female side of the buckle to the front part (
See photos for location).
Assemble both sides!
This mainly involves placing pockets where you want them.
If you want your pockets to span the entire width of your backpack like I do, don\'t bother connecting them now ---
When you sew them in the rest of your backpack, you sew them in the seam.
Assemble the triangle!
These are the parts of the triangle that will be sewn in the seam between the side and the back where you can connect the nylon so that your straps can be attached to your backpack.
Cut four triangles of equal size, nail the edges down, then insert your nylon strap into one of the short edges of the triangle.
If this sounds confusing, please check the picture for details.
This is how your strap is attached to the bottom of the package.
Assemble the bottom!
The only thing I do here is cut the other square at the bottom from the durable tear-proof nylon, adding a layer of thickness to the most durable part.
If your fabric is thin, you will seriously consider adding some extra fabric to the bottom because it will bear the maximum weight.
I also added 1/2 \"foam to the bottom between two layers to protect all the time I put my laptop in my backpack.
Assemble the straps!
There are many options here.
For the teal backpack, I sewed two tubes, turned them over and filled them with foam to make the backpack strap.
For a slightly smaller floral backpack, I just used two \"thick cotton straps \".
Again, you can use the straps as you like ---
I chose to add reflective material on the teal backpack (
Since this is a backpack for me to ride a bike, visibility is very important! )
And, there is also a nylon strap where I can attach flashing lights at night.
Can be elastic, D-
Ring with hook key or something else you want.
The most important thing is your comfort!
Once your straps are made, you will want to sew a three glide at the end, as shown in the figure.
This is where your nylon strap will pass, making the backpack an adjustable strap for the backpack.
Assemble the back!
This is the most complicated part.
After all, because the front is the most important, they don\'t call it the \"back\" package. . . .
First of all, you will want some padding: Pin Your 1/2 \"foam in the back, right inside your seam allowance, up to 17 \"(
The actual body of the backpack does not include the rolling part).
Then you can cover it. -
If I put a scratch cloth, I find it easier (
I used the old T-shirt)
Inside part.
As you can see here, I just quilted it in a simple diamond shape, but you can be creative here if you want.
Next one at the back: assemble the straps and handles!
Depending on the picture, you need a thicker nylon strap (1.
5 \"1\" can work if you have, but if you don\'t).
The strap will be sewn to the top of the back, right above the quilting section (
The bottom of this strap should touch the top of the quilting section)--
But don\'t look at it now!
Cut the 8 \"nylon to form the handle of the backpack and place it in the center of the nylon belt on the back.
See picture of handle placement.
Next to the handle, nail the strap in place.
Now, in the same layer as your strap, you will also pin the 8 th of Your nylon strap to the male buckle.
Soon, now a nylon, you should have two Velcro straps with a handle in the middle, coming out of the same place of the Velcro strap, two nylon with male buckle ends, this will be the other end of your rolling top fastener.
It sounds complicated, but just look at the picture-
You can easily see these places and understand why these things are here.
Sew the backpack strap, nylon male buckle, and the end of the handle onto nylon.
Then nail that piece of nylon on the back panel and align the bottom of the nylon sheet with the top of the quilting section.
Sew it in place
It will be hard to sew because you have a lot of stuff sewn here!
If you\'re using no-very-
Household sewing machine.
Take your time, lift your Press foot at the bumps where the strap is located, and don\'t be afraid to walk back and forth several times in the same area.
In fact, sew this nylon tape on your back at least three or four places.
This is something you don\'t want to sew.
Look proudly at the back of your finish!
Now you have a back with padding & you can walk around with it with a cool handle! Rad. So rad. Good job, you. So yeah!
You have everything now!
Just sew them together!
It\'s no secret.
Use a lot of pins.
I personally sew the bottom and sides first and then the front and back together, but there is no reason why you don\'t sew the front togetherbottom-
Then go back to both sides together.
Whatever your ship is.
You will also sew your triangles here: when you sew the sides to the back, pin them to the back at the bottom of the quilting section.
Your side bag is also stuck with these seams.
Nail a lot of needles to make sure that you can grab the fabric layer of the residence when you sew.
It may be a good idea to check these seams several times. Go slowly.
Use a large number of pins (
Like, dozens of pins).
The corner will be tricky (
I made them more U-
Several molding reinforcement).
Note: you will have a fully functional backpack when you finish this step.
However, it won\'t line up.
It\'s really tempting to stop here because everything seems to be done.
Stop here if you want. . . But! Don\'t!
Please sew a lining!
Otherwise, your computer, books, pencils, and backpack stuff will poke holes in your external fabric, tear your foam backing, and won\'t be waterproof at all.
Even if you are not interested in a waterproof backpack, the liner will put all your internal pockets there ---
Whatever you want, your laptop pocket, pencil pocket.
So the liner is a bit tricky. To sew. Hahahaha. So, sew.
Well, it\'s late.
Simple version: cut the rectangle on the front, back, bottom and side.
Assembled into a cube opened at the top, the seams are facing out.
Insert the cube into your shell, fold the top and sew the lining into the backpack. Voila!
Your Backpack is full and ready! Medium (waterproof)
Version: As above, only you absolutely use waterproof fabric (
I chose the TARP, it was light and kept dry but noisy and messy.
Use the seam when you finish the rectangular sewing-
The Packer sewed your edge outside (
There is the wrong side of your fabric)--
Or the real seam.
Sealing or tape. (
I\'m from yall, Kentucky.
Of course I have secret tape seams. )
Expert version: pocket seam!
Cut a 17 \"long, 25\" Long Pocket on your back, a letter envelope for a laptop.
Add some slender pockets to the front of the pencil.
Add a zip pocket for the expert hard version (oooooooh).
For the professional super hard version, sew the laptop pocket, pencil bag, etc. together with waterproof fabric, and then seal the outside edges so that they can remain waterproof. (
Statement: I have done medium waterproof version twice & no expert version ever. )
All the pads are the same. -
From the wrong side to the wrong side (
When you look at the bag, the seam is outside the bag, which means that when you look at the inside of the bag, you will see that there is no seam sticking out).
Fold the top of your outside and stitch it to the inside.
Fold down again (
Double Fold to hide rough edges)
Stitch again.
Now you have a backpack! Look at you!
Throw all your stuff in there!
I\'m proud of you.
I\'m proud of us. Have a martini.
Use your waterproof backpack in the rain, you crazy animal. You deserve it.
This is my baby backpack!
Teal is the first teal I have ever made with cordura and I found out in sales.
Here I visit Portland with it, or the most beautiful city of bikingist.
By contrast, I put it next to my boyfriend\'s North Street bag (
They also made rad bags. -
His is pannier\'s convertible backpack, which I don\'t think is brave enough this time).
You can see that they are about the same size, but I prefer the double straps on the top.
I also put more reflective accents for extra safety.
The flower is a birthday gift for a friend!
Take a picture, you know you want to take one, you take one, and now you are very proud!
I\'m proud of you.
