Although, paper towel tubes are quickly becoming harder and harder to find in our house, I do manage to snatch the ones we use and turn them into something usable. My new favorite way to use these is to convert into knife sheaths. We have a few knives floating around in our drawers they were just waiting to do some damage to unsuspecting fingers. To remedy the problem I just flattened the tube, cut to size, and taped an end shut. Now we can rest assured that no fingers will be lost.
