How can I create a splinter free and water proof piece of plywood for finger painting experiments?
I want to create a large surface for painting and finger painting for my toddler and would like to make it out of plywood coated in wipe able/washable paint. It needs to be water resistant/proof so that I can wipe it down between uses and, of course splinter free, lol. Any suggestions are welcome and appreciated! Methods, material suggestions, etc...Thanks!
