I've envied my brilliant friend Carol's rolling art cart (hers is a thrifted drink cart I think) for a long time. I tried to get by with a tiny little 6 x 20 three shelf piece of garbage I got at the hardware store but it was a joke - spewing paper and crayon bits all over the floor. So while at Ikea we picked up this dealy bob.. the antonius, for $4! plus 2.50 for shelves and maybe $2 for the wheels. We are ready to go. I love this solution because I can never guess where the kids are going to want to do projects, living room floor, dining room table, their bedrooms. This way they can roll all their supplies wherever they need to go!
