I wanted the butterfly bead to hang unsecured within a ring of tatting. That turned out to be slightly more difficult than I envisioned. A single beaded ring large enough to contain the butterfly was unstable and ugly. My next thought was a ring of inward facing rings, but I couldn't see how to attach the butterfly. Putting it on a picot would mean too much thread showing. Plan three worked - outward facing rings with the butterfly hanging from a chain. I threaded the butterfly bead onto the chain thread, then threaded a small bead on and went back through the butterfly. I could move that 'stack' into position, when I needed it. The same technique I used here. I read Patty D's explanation on In Tatters, but Corina Meyfeldt has also explained it.
