Jean, this idea isn't very original or "exciting," but I have an aunt who used to make lots of wedding/bridesmaids dresses. She took the leftover satin, taffeta, silk fabrics, cut them into squares, quilted them to flannel backing using decorative stitches (SID) and used them as bed coverlets. Nothing fancy but looked nice on her guest beds. Some pieces she put to use in pillows with lace trimming. I know you'll find some use for those fabrics!
