Last night, I had about a 1/2 C. of avacado leftover from dinner. I was too full to eat it. The other day I found a cucumber not rotten, but a bit soft for my taste. What to do with a used tea bag? 2 tblsp of the last scrappings from a mayo jar? I've always read here and there in magazines about these items being used for beauty products. Just curious if anyone ever use these, or any other leftovers for beauty products? Any favorite tips to pass on?
