A pretty cool accessory that's simple to make.
Step 1: Get Materials
Soda can tabs. Lots of 'em.
Optional: a clasp of some description.
Step 2: Cut Tabs
Cut the top of every tab on either side. (It takes a while)
Step 3: ASSEMBLE THAT SHIT
Connect the tabs top to bottom in groups of 2 or 3, depending on how thick you want it. You can also add some colored tabs if you have them.
Step 4: Safety Pin Clasp
You can use a safety pin to close it instead of killing your hand trying to put it on.
