Here it is, the final clue! I was going to split this up and give you the last clue next week, but it makes no sense to do it that way.
Decision points for the instep:
1. Repeat the chart from last week's clue over and over until your foot is the right length.
2. Repeat only part of that chart.
3. Work in Stockinette.
So, go forth and knit the fourth clue!
Heel flap is worked on 30 sts on needle two.
At the end of needle two, turn work so that the wrong side is facing you.
Row 1. Sl 1 purlwise, purl to end of row.
Row 2. *Sl I purlwise, k1*. Repeat from * to end.
Repeat these two rows until 27 rows are completed. You are now on the right side of the heel flap.
Note: Sl 1 = sl 1 purlwise
Row 1: (Right side) K 17, ssk, k1. Turn
Row 2: Sl 1, p5, p2tog, p1. Turn.
Row 3: Sl 1, k6, ssk, k1. Turn.
Row 4: Sl 1, p7, p2tog, p1. Turn.
Row 5: Sl 1, k8, ssk, k1. Turn.
Row 6: Sl 1, p9, p2tog, p1. Turn.
Row 7: Sl 1, k10, ssk, k1. Turn.
Row 8: Sl 1, p11, p2tog, p1. Turn.
Row 9: Sl 1, k12, ssk, k1. Turn.
Row 10: Sl 1, p13, p2tog, p1. Turn.
Row 11: Sl 1, k14, ssk, k1. Turn.
Row 12: Sl 1, p15, p2tog, p1. Turn. You will have 18 sts on your needle.
As you work the gusset, you get another point to make a decision on the instep: Do you repeat the leg chart from last week over and over, do you repeat just part of it, do you work it in stockinette? I won’t tell you what I did because then you’ll do it, instead of making your own decision. And you know what? Now that I completed the sock, I’ve changed my mind and will redo the instep. That should keep you on your toes!
Work across the heel flap sts on Needle two. With the tip of Needle two, pick up 14 sts along the side of the heel.
Pick up a stitch from the row below the first instep stitch to prevent a hole: 15 stitches picked up.
Needle one: Work across the 30 instep stitches in pattern. From now on, the instep only will be worked in pattern.
The foot will be worked in stockinette. You will have 30 sts on needle one and 30 sts on needle two.
With the point of needle two, pick up a stitch from the row below the first heel st to prevent a hole.
Pick up 14 sts along the right side of the heel: 15 sts picked up. Place a marker half way across the foot sts. This will help you count your decreases accurately.
Work across the foot sts and the instep sts. You are now ready to begin decreasing for the gusset.
Dec. round: At beginning of needle two (foot sts), k1, ssk, work to 3 sts before the end of needle two, k2tog, k1.
Work the instep in pattern. Do not decrease here.
Work the next round without decreases on the foot.
Continue to decrease on alternate rounds on the foot sts. Work until 30 sts on the foot remain.
Needle one: instep
Needle two: bottom of foot.
Continue working in rounds in until the sock is about 1.5 inches from the end.
Round 1: On needle one, k1, ssk, knit until 3 sts before the end of the needle, k2tog, k1. Repeat on needle two.
Work the next round plain.
Work these 2 rounds until a total of 20 sts, remain. 10 stitches on each needle.
Holding needles one and two together, graft sts on them together using the Kitchener st.
Weave in ends on inside of sock.
Work the second sock.
Correction: Miz Annie pointed out to me that I put in a decrease where there wasn't meant to be one. Sigh, and piffle to me. It's all fixed!
