I'm with you, Cathy! Linda Hahn of Frog Hollow Designs was a guest speaker at our guild and she's not troubled by backing matches either. She found a darling frog print and bought the whole bolt. Then she backed everything with it!
Our bee does only charity quilts. I am the main "backer" and I can't afford to angst over the backs. I generally can find a good match within our donation fabrics or my stash but I can't spend much time when often I have 30 or more tops every month to find backings for. Linda's presentation really was freeing for me!
