Use a purchased wire frame (of any shape) or follow the instructions for creating a wire frame in project: https://www.wirejewelry.com/jewelry_making_patterns_tutorials/Crystal-Waterfall-Pendant_345.html
Using your flush cutters, cut a 30" of 28 gauge wire and wrap around the left frame edge. 1/4 " down from the top and wrap six times leaving a 2" tail. Using the chain nose pliers, carefully squeeze the wraps together so they're tightly next to each other.
*Your wire may kink up while wrapping, use the nylon jaw pliers to smooth out your wire during this process.
