This was in my mind's eye for a couple weeks (or more) before I finally got around to making it.
I used some inherited thread (seems slightly thicker than Size 10) and a Size 7 hook. There are 5 chains between each bead and just under 100 beads for my 3-layer necklace. Not bad for $2.
I wore this on Sunday with a cream-colored sweater (forgot to take the picture that day...), and I was a little nervous that the wooden beads would discolor the sweater, but there were no issues. My only caution to you is to move them around as little as possible before you crochet it. The rough inside of the bead tends to "grab" at the thread a little bit, and you occasionally get some brown bits coming out.
