The materials you will need will depend on how big and long you want your rack (or how much wood you have). I had enough wood to make a small one (15'' long x 13'' tall)
1/2'' or 3/4'' plywood or hardwood
branching branches ( I used 6)
nails and/or screws (1'' or so will do)
2 hanging hooks
saw
handsaw for cutting the branches
table saw, miter saw, chop saw, or handsaw to cut the frame.
