My parents found some clever paper blinds at Home Depot with adhesive strips for their new home. For a few dollars, they've now got perfectly reasonable and nice looking window coverings until they have time to pick out something permanent for each room.
The boys were very happy to receive the remnants, which they turned into weapons, of course. In this case, machine guns, which I'll admit was pretty funny because of the way the paper sounds as the folds fall to the ground.
Fortunately, they turned the paper folds into fans next, and created a nice breeze for each other. It's good to see some peaceable creations too!
