Birch plywood panels

Are you paying through the nose for birch plywood panels for your wood burning and mixed media needs? I discovered that you can buy a big sheet of birch wood paneling at Home Depot or Lowes for under $10! That is enough to make many, many panels. Don't have them cut it up for you, though, because they charge around fifty cents a cut. Either invest in a saw or get a friend to do it for you . BIG savings, you guys!
