- thin wood boards (used to be called hobby boards at Home Depot)
- thin nails
- sand paper
Head over to Home Depot (or another store that carries wood and has helpful employees) with your canvas dimensions. I was creating frames for a 30x40 canvas and wanted to make sure the edges of the wood pieces overlapped each other on the edge so, I ended up getting the 40 inch long boards cut to 41 to accommodate for the overlap. I found a helpful employee and he cut them for me for free!
Once I had 4 of each length (I was framing two canvases.) I headed home with my wood and grabbed a box of small nails on my way out of the store.
