I am having the same problem as the original poster. I've knit many many socks in the round before. It seems that this pattern is getting you to knit the slipper flat, and to sew up the seam when you're done. Also, (and I could be wrong) it seems like since you're adding the leather sole, you're making these slippers without bottoms? I could be wrong, but the seam stitching is only for the cuff, heel, and gusset, and not the foot of the sock. I have spent an entire week now trying to figure out the next part of this pattern, and I'm so lost - and SO frustrated with having to keep ripping stitches out to try something else. Here's the rest of the pattern (I'm using different numbers of stitches due to different sized yarn, but the instructions are the same):
Knit across 17 (19, 19) sts. Place rem sts on holder for instep.
Work heel flap in St st for 2 ¾ (3, 3) inches; end with purl row. Bind off next row (knit row) tightly. Place last st on right ndl.
GUSSET AND INSTEP
With RS facing, pu 8 (9, 9) sts along inside edge of heel flap(1st st is already on needle)- 9 (10, 10) sts. Knit 2 sts from holder, pm, work in est ribbing pattern across 13 (15, 15) sts (from holder), pm, knit last 2 sts from holder. Turn. CO 9 (10, 10) sts for other gusset. 35 (39, 39) sts.
Row 1(WS): sl1, P to marker, rib to next marker, p to end.Row 2 (RS): sl1, K across gusset sts to 2sts before marker, k2tog, rib to next marker, (sl1, k1, psso), knit to end.(2 sts dec'd)Repeat Rows 1 & 2 until 6 sts remain in each gusset section- Total 25 (29, 29) sts.Rep Row 1 (WS) one time.
Row 1 (RS): sl1,(p1,k1,p1,k1,p1),slip marker, k to next marker, p1, k1 repeat from * to end.
Row 2 (WS): sl1, rib to marker, purl to next marker, rib to end.
Repeat Rows 1 & 2 for 7 (7 ½, 8) inches from beginning of gusset shaping. End with WS row.
Row 1(RS): sl1, rib to marker, (sl1, k1, psso) 2 times, knit to 4 sts before marker, k2tog twice, rib to end. 21 (25, 25) sts remain. (4 sts dec'd)
Row 2(WS): sl1, rib to marker, purl to next marker, rib to end.
Repeat Rows 1 & 2 – 1 (2, 2) times. Remove markers on last WS row - 17sts.
Next RS row: sl1, rib 3 sts, (sl1, k1, psso) twice, k1, k2tog twice, rib to end - 13sts.
Next WS row: sl1, work as est in pattern.
Next RS row: (sl1, k1, psso) 3 times , k1, k2tog 3 times. (7sts)
BO all sts in purl.
Sew side seam of cuff, heel and gusset. Center heel on back seam of slipper bottom and center toe on front of slipper. Pin evenly around (safety pins or split ring markers work well). Use Whip Stitch to sew slipper to sole. [/COLOR][/I]
So I've knit the heel flap, so I have what looks like a rectangle (the open cuff) with the small heel flap rectangle attached to one half of it. I can't for the life of me figure out picking up and working on the gussets. I can pick up the stitches on one side, and rib across the 'inseam' (where the stitches remained on one needle, at the very beginning of 'beginning the heel'.) But then I'm left at the end of the row... and the other side of the heel flap is on the other side of the row, so I can't figure out how to connect it unless I join the edges and start knitting in the round.
Anyone have this figured out? I've searched a zillion websites, and youtube, and found nothing.
