You usually see this stitch being used on cuffs, hems and necklines. This is a reversible pattern cast on an odd number of sts.
For this swatch I cast on 15 sts.
Row (RS)1: k1, *p1, k1; repeat from *to end
Row 2 (WS): p1, *k1, p1; repeat from * to end
Repeat rows 1 & 2 until piece is desired length. This swatch is 6 rows.
Before I formed you in the womb I knew you, before you were born I dedicated you... Jer 1:5
