Place a toothpick under the end of a roll of packing tape or duct tape, it will be easy to spot the end and get it started the next time you need to use it!
Packing tape, especially the clear stuff is really hard to find the end again. If I don't have a toothpick handy I'll fold the end of the tape under (sticky sides together) so it's easy to find.
