When counting your rows in flat peyote stitch, you will count the last two beads on the outside edge of the beadwork. To correctly count the number of rows, you will need to zig-zag back and forth between the bead on the outer edge (outside bead) and the bead next to it on the inside (inside bead) of the beadwork.
The rows in flat peyote stitch cannot be counted in the same way as the rows in tubular peyote stitch.
Do not try to count the rows of flat peyote stitch in the middle of the beadwork. It is easy to become disoriented and lose your place, particularly if you are working an intricate pattern with several different colors.
