Ladder stitch: Making a ladder, traditional method
1. Pick up two beads, and sew through them both again, positioning the beads side by side so that their holes are parallel (Figure 1, a–b).
2. Add subsequent beads by picking up one bead, sewing through the previous bead, and then sewing through the new bead (b–c). Continue for the desired length ladder. This technique produces uneven tension, which you can correct by zigzagging back through the beads in the opposite direction (Figure 2).
