Step 2: Find your Glass
Step 3: Wire
Take your wire and make a loop with it. This loop will be what your pendant hangs from, so don't make it too big. Take this and position it at the top of your piece of glass. (the side you want it to hang from) Then wrap your wire around your glass a couple times, wrap it in different directions to ensure stability. Take the end of your wire and wrap it aroung your loop twice, back around your glass, and around your loop again. Cut off any extra wire and tuck the end under one of the loops on the back of your glass.
Step 4: Finished!
