Crochet and tape creations are an old, very time consuming craft and these date likely from between 1930 and 1950. This work is done by crocheting together purchased bias tape, rick-rack, etc. It's really amazing what an artistic person can do! These lovely pieces can either be permanently fixed to a dress, sweater, sweatshirt, etc. or just pinned on when you're in the mood! Pinning them on makes it really easy to keep them laundered. And…they wash like a charm. NEAT!
