The River Pebbles Headband features the 2×1 broken rib stitch, that is only a 2-row repeat. The headband is knitted flat.

The first and last 3 stitches form an i-cord edging, that makes the edges look neat and prevents them from curling.

The the cast-on and bind-off edges are seamed together forming a decorative twist in the middle. The seam is hidden by the twist and is not visible.
