A few things I have learned:
1) Pickle jars (and a few other food items) will always smell like what was in them - no matter how many times you wash them!
2) You never know when you are going to use some of that random craft stuff that you have laying around.
3) Never throw away your paper towel rolls if you cut vinyl because after you cut your design, you just roll it up and put it in one of those and you don't have to worry about it getting ruined!!
