I have only done this once, but learned quite a bit in the process.
First, I would recommend making a 3mm thick circle the diameter you want for your finished piece.
Then, grind the pot melt into a perfect circle.
Then cut one or two rims (depending on the thickness of the melt) as in Patty Gray's tutorial that Brad indicated. Make the inside rim about 1/8" larger in diameter than the pot melt.
Place the melt in the center of the blank with the rim (or rims) around the melt.
Fire to full fuse.
Hope this helps
Steve
