Out of curiosity I picked up a small sheet of copper. Wanted to try covering something with it but the wife couldn't think of anything she wanted done.
So, I grabbed an old wooden bowl I never finished and just started hammering.
Ain't much but I enjoyed making this sort of square bowl. ~5".
Not sure this qualifies as metal working so I put it here.
(EDIT: moved to metalworking, as per Bill's note. JKJ)
