Increases are usually made between stitches. In the first increase round, pick up a single bead between the stitches (Figure, a–b). You will not stitch through these single beads; they are used to fill in the space between rounds. In the next round, pick up two beads between the pairs of beads (b–c). In subsequent rounds, work in tubular herringbone with the increase pairs as bases for new stacks of beads (c–d). The increase stacks may initially seem shorter than the other stacks, but they will catch up as you work additional rounds.
