I cast on and did the first garter stitch rows this morning.
It's very hard to get into any kind of a rhythm with this cast on, which makes counting difficult. I ended up marking every 10 stitches with a flat slide on marker. At least then when your bead doesn't fit, your stitch slithers away from you or you get interrupted, you can figure out where you are fairly easily.
Best of luck, cherry blossom sisters.
