My 3.5 year old loves to post her artwork on our walls. It started with a picture she made at a fall festival a few months ago - we tacked it onto a wall in the living room with painter's tape - and ever since then she wants to put up her art anywhere she can find an empty wall space. As a result, we now have that initial wall full of paper and she's now spreading out into her bedroom as well. I've generally rolled with it, but it's going to start getting out of control pretty soon. Anyone find any creative solutions for kids who like to show their stuff off like this?
