Forged from 2 1/2" x 3/8" flat stock, tapered to the top and spread out at the bottom under the power hammer. I like to leave lots of texture and sand the high spots to give the piece more interest. The shelves are 8", 10" and 12" long by 5" wide. At the widest point the shelf is about 18" and is about 48" long each one differs as they are all hand made one at a time. The shelves are a semi-transparent acrylic, the metal is finished with bees wax and linseed oil.
