I'm using a pretty neat little tool that I bought last year. It's the "Fleegle Beader". Wasn't real sure how I'd like it. I love placing my beads with a crochet hook. Thought I would give the larger one a try with the size 3/0 beads I'm using. Gotta say, I'm pretty impressed with it. It can hold quite a few of the larger beads and it's been holding the yarn rather nicely so I can simply slide a bead over the tip and onto the stitch. The yarn rests in a small notch at the tip. Will it replace my crochet hook? Don't know.
