I keep thinking of ( not just for Halloween) of using the laser on craft sticks ( Popsicle sticks - tounge depressors or whatever name you use). What you do is line them up in a row (flat) so they make about a square, then just engrave a vector image on them ( for Halloween a witch, mummy,ghost, etc.) then flip them all over and engrave another image. When done pull out all the sticks ( I’d assume about six to ten of them?) and you have a neat 2-sided puzzle as you try and arrange them in order/side. May even be difficult for older kids if 2-sided!. What do you think? Kids could even color the artwork with markers before or after.
