Laminate summer camp packing lists
Aliza's hack would also work well for back-to-school supply lists (not that anyone's thinking about school right now):
My daughter has been going to camp for the last couple of years. Each year the camp sends me the same packing list and each year I lose it and have to print out another one (or two). This year I took the list and laminated it. That way I can check each item off the list with an erasable marker and write notes on it too! They won't get lost because I will toss them right in her trunk when she gets back from camp (along with all of her other stuff that she uses just for camp).
