Step 1: Materials.
I recommend you to take a thin and big piece of paper because it will get smaller with the folding and folding which gets it thicker. if you use a small and thick piece of paper it would be a little bit harder to do.
Step 2: Folding. Part 1
Step 3: Folding. Part 2
Step 4: Folding. Part 3
as you can see, by now, this steps are exactly the same to make the famous game (which I don't know its name in english because I'm latina haha... in my country it's called "cortapicos y callares" or something like that).
Step 5: Folding. Part 4
everytime folding this become trickier because it gets thicker and thicker.
Step 6: Folding. Part 5
Step 7: Folding. Part 6
1. the four remaining triangles belong to (watching backwards) an upper and lower folded triangle shaped wing. take them (for 2 of the 4 triangles left) and unfold them as shown.
2. now seems like it's a whole new big triangle. unfold it too as shown.
3. take the lower half of that and fold it to center, just like in the picture.
there you have the arm of the jacket!
4. repeat steps 1, 2, 3 from folding step no. 6 to have the other arm.
Step 8: Almost Done!
ok... now, you can decide to make it a whole jacket and take advantage of the front side of it which it would be for the pants and corset. if it is so, to have your corset and pants you just have to fold your jacket by the half and it's done!
Step 9: Now That Is Done, Customize It! :)
Step 10: Extra! :D
once all steps done, unfold it completely. be careful with paper.
you should have something like I have in the picture number one of this step. then follow the pattern of the next picture (blue and black lines are just for contrasting) and fold it again taking in count the most coloured side is in the very first folding step, the back.
hope I made myself clear and you guys liked it. ♥
