Having issues figuring out part of a pattern I'm working on.
The pattern can be found here:
The part I'm having trouble understanding is this section:
Cut yarn leaving long tail. Thread tail through remaining sts and pull tightly to secure. Sew back seam for 2 (2½)" down from crown. Remainder is left open and becomes the lower edge of hat where the strap is worked.
With A, cast on 12(20) sts, pick up and k21(27) sts across left side base of hat, pick up and k1 st in seam, pick up and k21(27) sts across right side base of hat, cast on 12(20) st–67(95) sts.
Work 3 rows in Garter st.
Buttonhole Row 1: K2, yo, k2tog, k9(17), yo, k2tog, place marker, k to end.
Buttonhole Row 2: K to marker, yo, k2tog tbl, k9(17), yo, k2tog tbl, k2.
Work 3 rows in Garter st. Bind off.
I followed the pattern and got to the end of the "shape back" part. I threaded the yarn through the open stitches but haven't sewn the back shut yet because I'm confused about the part with the strap and don't want to mess it up.
Can anyone put this to me a little more simply? Still fairly new to knitting.
