I bought this really funky black trim with silver rings at Fabric of Vision in Ashland, Oregon while on vacation. This 10-card series has a variety of metal pieces - colored safety pins, old watch parts, paper clips, beads, bolts, spacers, other trim, tulle, netting, household screen and clock hands. You will need an envelope to mail these one-of-a-kind cards. Each card is backed with felt. I find that making these small cards sometimes gives me ideas for making larger pieces. These were quite FUN to make.
