1. To begin the first cube, work three right-angle weave stitches. Join the first and last stitches to form a ring: Pick up a bead, sew through the end bead in the first stitch (Figure 1, a–b), pick up a bead, and sew through the end bead in the last stitch (b–c). Figure 2 shows a three-dimensional view of the resulting cube. To make the cube more stable, sew through the four beads on the top of the cube (Figure 3). Sew through the beadwork to the bottom of the cube, and sew through the four remaining beads.
2. To make subsequent cubes, work off of the four top beads in the previous cube (Figure 4): Exit one of the top beads.
See photos for the following instructions in the gallery below.
For the first stitch: Pick up three beads, and sew through the top bead your thread exited at the start of this step and the three beads just picked up (Photo a). Sew through the next top bead in the previous cube.
For the second stitch: Pick up two beads, and sew through the side bead in the previous stitch, the top bead your thread exited at the start of this stitch (Photo b), and the next top bead in the previous cube.
For the third stitch: Repeat the second stitch (Photo c), and continue through the side bead from the first stitch.
For the fourth stitch: Pick up a bead, and sew through the side bead in the previous stitch and the top bead in the previous cube (Photo d).
3. To complete the cube, sew through the beadwork to exit a top bead in the new cube. Sew through the four new top beads to stabilize them (Photo e).
4. Repeat steps 2 and 3 until you reach your desired length.
