I've been wanting to make this since forever! Got the idea from Dream, Create here.
You're gonna need silicone molding putty, polymer clay, a starfish, spray paint color of your choice, and a glass slightly smaller than your wrist. Mold the starfish, put clay in mold, wrap clay starfish around glass, bake at 275 for 15 minutes, decide to bake it for 7 more minutes just in case, burn yourself while removing starfish from glass due to impatience, spray paint starfish, and you're done!
In retrospect I wish I would've made the legs a bit longer so it would fit more securely. Also, this happened the first time I used the silicone putty.
Lesson learned: blend faster. Mold faster. Don't end up with a blob of useless bouncy stuff.
All materials were from Michael's. It would've cost me $17, but the girl at the cash register didn't add in my discount coupons correctly. $27...
