I learned how to do friendship bracelets while at camp (I had a lot of free time) but I just realized how to put a yoyo twist on it so I figured I should share it.
Step 1: Get a yoyo string
Step 2: Make a slip knot
Step 3: Make a slip knot through the slip knot
Step 4: Put your wrist into the slip knot (the order between step 3 and step 4 doesn’t matter so do whichever is easiest)
Step 5: Tighten
Note: You don’t need a lot of string to make a bracelet so you can turn your longer strings into multiple bracelets and share them with other people.
