Wax Paper Strips for Greasing Pans

I like to keep ready made wax paper squares with margarine or butter that I get out of an empty butter container or margarine container. I use the spatula to get the butter out and wipe it on the squares. I close the square over itself and then I put them in a sandwich bag. This way I use every last bit of the butter or margarine in the tub before washing it out and recycling it. I found out how much butter is saved this way rather than just washing the tub and wasting all that good stuff left in the margarine tub.
