Materials - gum wrappers (at least 4, preferably more), ruler (optional), a rounded object like a marking pen.
Why? I have no idea.
But, have you ever challenged yourself to do something you didn't think was possible? I mean like making something that no one else has ever done. I don't know if anyone has made things like this before. I've seen a few examples where woven chains of wrappers have been used to sculpt various things. They usually use fish line to tie them together. I try to make things with just the wrappers and nothing else. No glue or tearing of the pieces (I have cheated on some). It's very challenging and rewarding to think up designs and solve the problems of making them stay together simply with folds (quite similar to origami I guess).
Please enjoy my simple example here, let me know if you want to see more, and please try out your own designs and share!
Step 1: Fold Some Sticks
Fold in half lengthwise. Try to make the fold as exact as possible.
Step 2: Keep Folding the Stick
Step 3: Rolling the Stick
Repeat these first three steps for at least 4 sticks (2 sticks per chain link).
Repeat as necessary for more chain links.
Step 4: Measure for Half Way Point
Fold each in half to a 90 degree angle.
Step 5: Make the Spiral Connectors
Wrap the one leg of the bent stick around the straight stick. Keep wrapping around in a tight spiral wrapping outside the bend in the bent stick. Once you have wrapped the half leg of the stick around as many times as it will go, pull out the straight stick.
Repeat for as many bent sticks as you wish.
Step 6: Shape Each Half Chain Link
Step 7: Join the Half U's
It takes two(2) U's to make one chain link. Place one "U" flat and right side up. Place it's mate flat but upside down over the first one (kind of like an "n"). Make sure the pig-tails are on opposite side - left/right. The pig-tails form a female connector and the straight part the male. Simply mate the two haves together and you have your first link. (don't be embarrassed, you're just making chain links here)
Repeat as desired for additional links, but remember to first insert through one end of you chain or you will just have a bunch of ovals.
Step 8: Other Chains
You can also make smaller ones by only using 1 stick per link and simply making more bends to fasten to itself.
