Trying Chiagoo red needles for a change instead of my usual hiyahiya sock sharps.

Leg:
Cast-on 63 sts.
K2,p1 rib until 4” from cast-on, un-stretched.
Move start-round back one stitch so that first stitch is a p1.
Work 34 in rib patt, then work heel flap over remaining 29 sts.

Heel flap:
RS=sl1 Kwise, k1, sl1 Kwise, to last 2, k2
WS=sl1 TBL, purl to end.
Work until 18 sts to pick up on either side (36 rows.)

Turn heel:
12, 5, 12
Sl1, knit 11 + (5-1), ssk, k1, turn.
Sl1 pwise, purl 4, p2tog, p1, turn.
Sl1 pwise, knit to 1 stitch before gap, ssk, k1, turn.
Sl1 pwise, purl to 1 stitch before gap, p2tog, p1, turn.

Instep:
Pick up 18 sts on either side of heel flap. Continue the held 34 sts (top of foot) in established p1, (k2, p1) but use stockinette for all other sts.
Dec inside a 2 st border, every 3rd round 6x, then every second round until there are 64 sts total.

Foot:
Continue 34 rib sts on top of foot, and 30 stockinette. Work until 6.5” from heel flap picked up edge.

Toe: work all in stockinette and transfer sts to get 32 on each needle.
Dec ever 2 rows 2x, then every row until 6 sts remain. Graft toe.

Sock2 = 27g, 22 leftover
Sock1 = 26g, 22 leftover
