This craft is from the Disney Family Fun website. If you haven't seen this site before, it is an excellent resource for kids crafts.
This is the one I made. It started off being Amelia's but she lost interest because it was "a bit too twicky, Mummy". We decided to make them with only two sides of the folded paper because it was a bit harder than we thought it was going to be. The one I made could hang on the art string in the kitchen easier then too.
Ellamay and Esther both turned theirs into bunny houses. Ellamay's had staircases and striped floor boards.
Esther went with pink flooring.
And a bunny inside. The photo below he was having a sleep I think. He looks a little sick. Perhaps too many Easter eggs?
