Here's another way to look at this. You've made them a reversible tree skirt! Who knows, maybe next year they'll use the "right" side. I often do this when making table runners and wall hangings, especially around the holidays so one side will be Christmas and the other winter-related. In the fall, one side is Fall and the other is Thanksgiving. Truthfully, I started doing this because I was too busy to make piece and quilt two projects so I combined them into one. Congratulations on your reversible tree skirt being used and loved! :-)
