You know those rolls of clear packaging tape, that come with or without teeth cutters on them? the rolls that are about 1" wide, and are used to tape up boxes?
Well, when doing my last batch of box-taping, I saw how after cutting the edge would flutter off and stick to the roll again, making it a PITA to remove. So I decided to stick the fresh cut edge to another box or scrap paper. This roll didn't have the holder plastic to hold the tape in place, it was pure loose tape. Duh, secure the sticky edge!
