This year I decided to make mint tea bags for holiday gifts, and they were a hit. Simple enough, too: cut mint in late fall, dried on screens for a day or two, then stripped the leaves from the stems. Took a kitchen scissors to the dried leaves to make the pieces more manageable for bagging. Bought a pack of unbleached paper tea bags from Amazon (cheap) and filled them. I could fit two or three of these into an envelope with a holiday card for small gifts, but for bigger gifts I turned a couple of storebought paper tea cartons inside-out, then decorated the boxes as I liked.
I was inspired by this thread to not let the mint go to waste again at the end of the growing season. Thanks, fellow Mustachers!
