You need safety pins and a pair of tweezers.

The first thing you need to do is use your tweezers to bend back the thingy {yep, technical term} in the clasp.

You want to hook it to the fixed side of the new pin, not the side that opens. Once it’s hooked on, use your tweezers to bend the middle thingy {seriously, it’s a technical term} back to normal.

Continue repeating these steps until you have a bracelet that fits your wrist. The standard size for adult bracelets is 7-1/2″ long. Since I used size 0 pins, each individual set was approximately 1″ long, so I needed 8 sets {I tried to put it on after 7, and it was too small}. To put it on, just thread the first safety pin through the holes in the last one, just like when you were connecting the sets together.
