Cast on 54
Row 1: Knit across
Row 2: K25, P1, increase 1 in next 2 stitches, P1, K25
Row 3: Knit across
Row 4: K25, P1, inc 1, K2, inc 1, P1, K25
Row 5: Knit across
Row 6: K25, P1, K1, Increase 1 in next 4 stitches, K1, P1, K25
Row 7 and all odd rows: Knit across
Row 8 and all even rows: K25, P1, K10, P1, K25

Work rows 7 and 8 till you have 24 rows, 12 garter "ridges"
Bind off 16 stitches, Knit across
Bind off 16 stitches, K9, P1, K10, P1, K9
*knit across
** K9, P1, K10, P1, K9

Work the * and ** rows until you have a total of 25 ridges from heel to toe,
K2 tog across ,cut yarn with 3 foot tail, thread large needle with yarn, thread thru stitches on knitting needle, draw tight and sew up seams,

this pattern will be 8 inches, a bit higher than those pictured, I think the red and tan pair was started with 40 cast ons, good luck
