I decided to make a dry-erase board with a regular frame (it's approximately 2x3) because I read that dry erase markers work on glass as well. I papered the inside part with a cream colored confetti paper so I could see what I was to write clearly. I was about to put it all together and nail it up - and then I realized the glass part isn't glass - it's plastic. No matter, right? Wrong. I had tried the dry erase marker and it worked fine, so I set it all up and wrote some things, but the next day when I went to erase something, the words wouldn't budge. I tried scrubbing with a regular cleaner and the regular eraser thing but I can't get the words off. I'd rather this not be an effort wasted because I really like the way this looks, so does anyone know how to get marker off plastic? (Scrubbing with the eraser actually did more than the cleaner, but only removed a top layer. The cleaner did nothing, basically.) Thanks for any suggestions in advance.
