I've always assumed Scotch tape doesn't work well for fridge and freezer labels, but I've never actually tried it. Sarah's tape trick has me rethinking:
Turn over the end of a piece of tape before sticking on the label. It's super-easy to pull off when you are ready.
I find Scotch Magic Tape is especially good because it doesn't leave behind any glue and stays on even in the freezer. I started this system for labeling breastmilk bottles, but now I use it on everything that goes in our freezer. No more 'freezer surprise' dinners.
DUH. *forehead smack*
