I made this for a swap!
It was inspired by this piece
. I'm entirely addicted and am making all sorts of pieces from our wedding silverware now.
Edited to insert some tutorial information provided later in the thread.
I used the one on the right right to drill the initial hole and to drill out the entire star shape. I just looked it up in my Dremel's manual and it's the Tungsten Carbide Cutter. "These are tough, long-lived cutters for use on hardened steel, fired ceramics, and other very hard materials. They can be use for engraving on tools and garden equipment. 1/8" shanks."
I used the one on the left to sand all over in long, smooth movements. It made it super shiny and removed any ugly surface blemishes. I couldn't find that one in the manual, but I think it's some sort of grinding stone? Maybe someone will post here and tell me!
Edit with more info!
I bought the dremel cutting bit today at Home Depot. The part number is 9903 and cost around $7.50 in case anyone was wondering.
