’’My kids got these for Halloween. They are thin plastic, what are they?’’
Answer 1: "They are stencils, popular in the 90s. Got a bunch as a kid!"
Answer 2: "Yep, this is it, the raised lines are so that when you put a piece of paper over it and rub a crayon over it the raised lines show up darker for detail."
I have one that has been in use for over 80 years, there is nothing missing on it.
