Hi - I am in the same boat! I also have an Amazon gift card from xmas and am looking for some beginner tools/supplies to purchase for making earrings.
I was also gifted a few Amazon products to get started so maybe check them out if interested - liquid sculpey, Arteza 42 color oven-bake clay set, and a set of tools.
I am looking at getting some small cutters and some gold leaf sheets. I might also look for some kind of pattern roller (if that exists?), jewelry pliers, and something to sand down the edges of baked pieces.
