Shark teeth. So hot right now. Thank you Givenchy Spring runway!
What you'll need:
28 inches of chain
1 foot of wire
1 shark tooth (From Ebay)
Step 1 - Using wire cutters, cut 1 foot of wire. Create a wire loop (how-to here).
Step 2 - Holding wire loop against the back of the shark tooth, wrap wire around the right side then the left. Alternate sides 3 times.
Step 3 - Wrap remaining wire 3 times around the the loop you made in step 1.
Step 4 - Slip chain through the loop. Add clasp and jump-ring using pliers.
