You will need:
- 2-3 feet of memory wire (available from craft stores)
- Some narrow gauge wooden beads (preferably unfinished wood)
- A foot of acrylic yarn
- A pair of pliers
Thread a couple of beads onto the memory wire and bend it into a small loop behind them so they can't fall off. Do the same at the other end. Tie the yarn loosely around the wire and make a single crochet line for a couple of inches. Add multiple crochet sections if you prefer.
Use the wire like a fishing lure, making the crochet twitch around. My cats love this! The original toy had twisted paper tags on it, and they destroyed them. I just fixed the toy and they're playing with it now. One cat will pick up one end, and chase the other end in circles.
