CO 60 sts and join in the round.
Round 1-6: *k5, p5*, repeat between * and * to the end of the round.
Round 7-12: *p5, k5*
Repeat round 1-12 two more times, then start decreasing:
Round 1: *k2tog, k3, p5, k5, p5*
Round 2-5: *k4, p5, k5, p5*
Round 6: *p4, k2tog, k3, p5, k5*
Round 7-10: *p4, k4, p5, k5*
Round 11: *k4, p4, k2tog, k3, p2tog, p3*
Round 12-15: *k4, p4*
You should now have 48 sts.
Continue with 4x5 squares until you have the desired length, like this:
Round 1-5: *p4, k4*
Round 6-10: *k4, p4*
I made mine about 40 cm long.
The heel:
(I use the heel decreasing from Drops)
Put 24 sts on a separate needle and knit stockinette (RS: knit, WS: purl) back and forth. Decrease with one sts on both the first and second row = 22 sts, then continue stockinette for about 5 cm.
Heel decreases:
Round 1 (RS): knit until 6 sts remain, slip next st as it to knit, k1, psso, turn piece.
Round 2: purl until 6 sts remain, slip next st as it to p, p1, psso, turn.
Round 3: knit until 5 sts remain, slip next st as it to k, k1, psso, turn.
Round 4: purl until 5 sts remain, slip next st as it to p, p1, psso, turn.
Continue decreases like this with 1 less st before each dec until 12 sts remains.
Pick up 10 sts on each side of the heel decreasing, and join the work.
Continue the 4x5 st square pattern on the top of the foot, and knit stockinette over the rest of the sts.
On every other round, decrease one st on each side of the foot, using ssk on "the way up" and k2tog on the way down towards the heel, until you have 40 sts left.
Continue until about 2 cm from the tip of your toe.
Toe decreases:
Row 1: *k2tog, k4*
Row 2-3: knit
Row 4: *k2tog, k2*
Row 5: knit
Row 6: *k2tog, k1*
Row 7: k2tog
Pull yarn through the remaining sts and fasten.
