Really pleased you're inspired to make!
Best advice i would give you is to just make what you like not what you think other people will like. I have loads of things that will probably never sell but I had lots of fun making them and everything is practice. I do a lot of wire wrapping in copper, its a bit more forgiving on the hands and is super cheap so you can work without worrying about wasting materials. Let me know if you need any pointers, i'm not so experienced with soldering/stone setting but wire wrapping I may be able to lend a hand.
