Yep. All 324 of them. The secret is to only use the beads on even rows; slip stitch odd rows back to the other side. That way, the order of the beads is always the same; one doesn't have to plot complicated back-and-forth maps. So I can just mindlessly go "6 blue beads, 6 green beads, 6 blue beads. Next row: 6 blue beads, 6 green beads, 6 blue beads. Next row:" and so on, for 6 rows, then switch to mindlessly threading 6 green beads, 6 blue beads, 6 green beads for 6 rows - the sort of thing that, as an accountant at heart, I can keep track of effortlessly, so that I can string all 324 beads without conscious though, then start crocheting.
