Needed a new bag for school, so I made this one today. Kind of like how it turned out all sturdy and nice, and the pockets are really what I needed.
* One main case for books, lunchbox and stuff.
* One larger pocket at the back for my supply-case (see other thread)
* One pocket at the side for waterbottle and (in summer) a fan
* 3 smaller pockets of various sizes for loose papers, cellphone and stuff.
It's got room for everything I need, neatly organized.
(it is black, I swear. Just the light that makes it look all... grey/brown-ish)
sorry about the blurry pics... hate not having a scanner or proper camera.... Also I forgot the bottle-case on the inside in the instructions- but I'm sure you can work that or any other pockets you'd like all by yourself =)
1. Meassure the size you would like on your bag. (X=height, Y=widht, Z= depth, W= length of strap)
2. Cut pieces, you will have to remember to add seam allowance to all of course.: A should be Y wide and X times 3 + Z long. You'll need three of this one: One for the outside, one for the inside and one in stiffer material for the middle layer. (I've henceforth named them A1 for inner, A2 for middle and A3 for outer.
B: Z times 4 wide (minus aprox. 1 cm) and W long. (cut in which ever fabric you want for the strap)
C: Cut this in the inner-fabric.
D: Cut in which ever fabric you want for the pockets.
E: You'll need 4 pieces of this: two in the middle layer material (E1) and 2 in the outer one (E3)
F: 4 pieces of this, in the inner fabric. You'll need extra seam allowance on this. I did however make a typo in the picture, it's supposed to be only half of Z+ the extra eam allowance
3. First hem pieces C on the upper and lower edge (the longer sides) by folding the edge twice. Don't mind that it's now shorter than the original size of X now- it's supposed to be like that.
Now, put pieces F on each side of the shorter un-hemmed sides of C and sew together with a seam along the red line. This should reslut in the darwing displayed last of these.
4. Take pieces D and hem then just like you did with C- along all sides. Then take pieces A1 and A2 placed on top of eachother (A1 over) and attached first one pocket (preferrably with a seam in the middle to divid it) and then the other one on top of that.
5. Now, take the pieces you just sewed on and place piece CF on top of it (covering the pockets) Add pieces E1 on top of F and sew all four layers together. It's good if pieces F are a tad bit longer both at top and botton than piece C cause you don't want to attached that later, it would be messy =)
Now, try to continue sewing on the sides as to make the whole thing bag like. I'm sure you understand how to do this. make sure all the seams are on the outside, and that the inner fabric is on the inside.
6. Now repeat step 5 (with less amount of layers and corners and stuff though =)) with the outer fabric (this time the seams of course should be on the inside).
7. Take piece B and fold the two long sides towards the centre, then fold again at the center. Then sew a seam along each side to fasten it.
8. Now, take the strap and put it inside the first piece you worked on, make sure it's not twisted or such, and let the ends stick up at the sides of the bag. Then take the outer-piece you've made and put it inside the other piece. (the middle-layer should now be outwards, the inner layer in the middle and the outer layer on the inside. (the straps now sticking out between the inner fabric and the outer fabric)
sew along the edges marked in red here (the red mass marking the straps hanging out- be sure to fasten these very well). If you like you can round of the corners of the top-flap too. Be sure to leave a opening in the front for turning inside-out after!
9. This is kind of what it looks like when you turn it inside out.
10. and this is what it will look like once you've manage to turn it inside out. Now sew the front together, and if you like sew a seam along the other edges as well as to flatten them.
Easy as cake, hope my instructions and awful drawings made any sense at all.
