Place marker for beg of rnd.
Continue with 1 strand each of B and C held tog, and shape gusset as follows:
Rnd 1: Knit.
Rnd 2 (Dec): K to last 2 sts on first needle, k2tog; k across instep sts; on 4th needle, skp, k to end of rnd.
Rep last 2 rnds until 40 sts rem.

Rnd 1 (Dec): K to last 3 sts of first needle, k2tog, k1; on 2nd needle k1, skp, k to last 3 sts on 3rd needle, skp, k1; on 4th needle, k1, k2tog, k to end of rnd.
Rnd 2: Knit.
Rep last 2 rnds until 16 sts rem.
Divide sts evenly onto 2 needles (8 sts per needle). Cut yarn, leaving a long tail. Holding the 2 needles parallel with wrong sides of fabric together, thread a large-eyed blunt needle with yarn end and work as follows: Insert needle as if to purl into first stitch on front piece. Insert needle as if to knit into first stitch on back piece. Then follow steps 1–4 below.
1) Insert needle as if to knit through first st on front needle and let st drop from needle.
2) Insert needle into 2nd st on front needle as if to purl and pull the yarn through, leaving st on needle.
3) Insert needle into first st on back needle as if to purl and let it drop from needle.
4) Insert it as if to knit through 2nd st on back needle and pull the yarn through, leaving st on needle. Rep 1–4 until all sts have been grafted. When finished, adjust tension as necessary.
