I had recently used floral tape to fix up some silk "fall leaves" for a patio display, and I wondered if the floral tape wouldn't provide just enough tackiness without being too sticky. And I quickly found out that it is just perfect as a base for the crochet cover. It's easy to apply too, very forgiving. Just stretching it lightly releases the tackiness that makes it so useful in floral arrangements. And the single crochet stitches were now happy to sit on the hanger with no floppiness.
This project went from hopeless to successful in the space of a thought!
