If I don't have any, I just take a piece of tape and a couple folds of napkin or paper towel or tissue, and hey, I got a band-aid.
You know, they were invented because a woman kept getting small cuts all the time, so her husband took a long strip of tape and put cotton balls every so often, and she just cut off a piece when she needed it. Or at least, that's what I heard. It's probably complete bull, but oh well.
They fall off when they need to stay on, and stick on and pull out all the hair when they need to come off.
