re: Laser Puzzles

Thanks everyone. 
Alex I use spray glue to adhere the photo. I don't get any charing or evidence that the laser leaves behind. Using 3mm plywood makes them so they should last a long time, but I think the next few will be using poster board so they will be like the puzzles you can purchase. I didn't like anything I found on line, so I created the pattern in Illustrator. I have a SVG file for 9, 15, 36, or 99 pieces I have them made and if anyone wants files let me know.
I happen to have a dog that smiles, so that one makes me laugh.
