Then we cut a slit down the side and cut the bottom off of the bags to create a flat piece of paper.
That could then be cut to size, wrapped around the boxes, and taped on just like wrapping a gift (except, you know, not as pretty.)
Well until all three kids ran to grab guys to climb up to the top. Then it could really be called finished!
What I liked about tackling this project: it was simple and easy, the kids were learning, we had fun putting it all together, and we used items we already had and may have gone to waste otherwise!
