This was one of those things that popped into my head while I was at work and then I just wanted to go home and work on it. I simply googled crochet beads tutorial and found this video. When I made my own, as usual – I rarely actually follow patterns, I used embroidery floss and a random small crochet hook. Also, instead of stuffing mine with fluff, I used a hard bead inside. Once I was 3/4 through I put the bead in and finished crocheting the rest with the bead inside. I’m guessing this is also how people do those crochet and lace covered river stones.
