I got my beads at a local bead store and online. For this project you need a few cute chunky beads, claps (4 per band), rings, connecter bars, smaller beads and Stretch Magic clear jewelry cord. I have tried other brands, and this one just holds up the best without coming undone or stretching out.
Step 1: Design
Step 2: String
Step 3: Wear
It doesn't take a lot of time to do this project if you have the supplies! After I got the hang of it and did a few, it only took me about half an hour to make 1. Beware though that this is incredibly addicting, which is why I eventually had to ban myself from the bead store for a while because I was depleting all of my budget.
