Another use for dental floss

Just started my camellia shawl. It's silky alpaca lace yarn on size 4 needles. It starts out with casting on 383 stitches. Then on the second row of the pattern, beginning the lace work, you add beads. I bought the smallest crochet hook I could find. It wasn't small enough. So I reached for my handy dental floss and made a bead threader. These may be the slowest 34 rows of a pattern ever knit.
