Thanks all! I don't like using black for the backer board, So I always use a wood backer board. The size is 8-1/2" x 11". I used alder for the frame because thats what I had laying around. I used mostly flat blades, Olson 2/0R, FD UR1, and I used FD NS 2/0 spiral blades where flat blades wouldn't work.
