I used Bernat Handicrafter Cotton in Virgina Rose with size 7 needles.
Cast On 37 stitches or the pattern is in multiples of 4 + 1 if you want it smaller or larger.
Knit four rows.
Row 1 (right side): K4, K1, *YO, K2tog, P1, K1; rep from * to last four sts and K4.
Row 2: K4, P1, *YO, P2tog, K1, P1; rep from * to last four sts and K4.
Rep these two rows until desired length.
Knit four rows and bind off. Weave in ends.
