This one goes right along with the key ring trick from yesterday.  When dealing with rolls of tape, it's absolutely maddening when you accidentally lose your spot, isn't it?

Especially with thin, clear packing tape, it takes forever to find the tiny lip at the end of the roll.  Then you spend five minutes trying to pry the edge away; and if the tape rips, well, then you might as well throw the whole roll through the window and use a different one!

So try this.  It's a way to save your place on a roll of tape, using something you would probably throw away if you didn't know any better.  Check it out!
