A close up of the toe...
The pattern - to fit approx 18mths (24 mths)
I used a set of 4 2.5mm dpns and woolhunter BFL super sock wool which is a 4ply yarn. The tension isn't really important (well I don't think so as kiddies feet are all slightly different)
Cast on 42 (48) sts and join in the round
work 10 rows of K1 P1 rib (or 20 rows if you want a turned cuff).
pattern - rows 1-4 * K3, P3* repeat to end
rows 5-8 * P3, K3* repeat to end
work 3 (4) repeats of the pattern or length desired to heel
Heel flap -
knit across 21 (24) sts, turn
S1, purl to end, turn
*S1, knit to end, turn
S1, purl to end, turn*
repeat last 2 rows 8 (10) more times
knit 12 (14) sts, SSK, K1, turn
S1, purl 5 (6) P2tog, P1, turn
S1, knit to 1 st before gap, SSK, K1, turn
S1, purl to 1 st before gap, P2tog, P1, turn
repeat until all sts used up - you should end on a purl row. For the larger size I think you will have one gap left on the knit row, so just knit all the stitches on this row with no decrease 13 (16) sts on needle.
knit across all 13 (16) sts.
pick up for heel
N1 - knit 10 (12) st down side of heel, N2 continue in pattern on 21 (24) sts, N3 knit 10 (12) down other side of heel and 6 (8) sts from needle 1.
N1 17 (20) sts, N2 21 (24) sts, N3 16 (20) sts - 54 (64) sts in total.
next round (round 1)- N1 knit to last 3 sts, K2tog K1, N2 pattern across all sts, N3 K1 SSK, knit to end
next round (round 2)- N1 knit, N2 continue in pattern, N3 knit
repeat these two rows until you have 42 (48) sts
continue knitting as round 2 for 15 (19) rows or length required before toe shaping.
decrease for toe
round 1 - N1 knit to last 3 sts, K2tog, K1, N2 K1 SSK, knit to last 3 st, K2tog, K1, N3 K1 SSK, knit to end
round 2 - knit across all needles.
continue until 14 (16) sts left
knit sts from N1 to needle 3 - 7 (8) st on each needle and graft these together
