Sweet! I really like how you did the background.
Ah, well, ahem, yes... that's a multi-coloured foam kneeling pad for gardening that I just happened to put it on to take the photo. But because it looks OK, I think I'll paint some 1/8" ply in similar colours as a backer.
Keefie, I wish! I've never even attempted to sell anything, I'm happy just cutting them.
Thanks for all the comments.
