I'm currently testing the waters doing some Intro to Making courses in my area.

My latest bit of silversmithing - a pendant requested by my niece.
(I hate this one less than usual, but there are still parts I hate!)
Made from brass, sterling silver, and jasper.

Working on learning a technique I got from @jarkman.bsky.social - I've made a few dozen of these with various materials and variations and finally have one I'm happy with.
Will post many failures soon!
