I've been searching for a tack strip like they have in schools for all the kids' art. They're quite prolific and we have more art than we know what to do with and they/we're always wanting to put it up. The fridge is only so big.
So I got a free leftover bulletin board from work. Owa had art on it the second I brought it in the house, before I could even get it hung on the wall. It filled up on the first day, probably within the first hour or so. I'm going to add another somewhere else if I can.
