I have a lot of quirks that have developed out of my need to be frugal. One of them is saving my butter wrappers. Whenever I have softened a stick of butter for baking, I fold the wrapper up and stick it in the freezer. Then, when I need to grease a pan, I pull it out and unfold it. After a few minutes, the butter residue is soft enough that I can use the wrapper to grease my pan. Waste not want not!
