Flat Knit Sock Pattern

Here's a sock you can knit flat in rows.

I got the idea from a Facebook post, but the instructions were in another language, so I wrote this pattern based on how I interpreted the picture.

The knitting of this is pretty easy, but you do need to know the basics: purl, knit, increase and decrease.  It also helps to know how to sew knitted fabric, but I don't have any advice for you there as I'm still learning how to do it myself.

Anyhow, here's the pattern. Enjoy!

Flat Knit Sock pattern:
Makes a size 9 sock.
Use size I knitting needles.
Need a crochet hook for starting and finishing. H or I would work.
Recommend using 2 colors, one for heel/toe and the other for top/bottom/cuff. Helps tremendously when you get to the part where you have to sew it up to look like a sock.

Crochet chain 15 cast on (by this I mean, crochet 15 ch, then knit to draw up loops, ending up with 16 loops on the needle), or knit cast on 16 loops.
P across 1 row.

Work Heel/Toe Pattern:
Heel/Toe Decrease: Each k row, decrease 1x each end; p next row. Repeat these 2 rows until 8 loops on needle (ending on purl row). (1.5")

Heel/Toe Increase: Each k row, increase 1x each end; p next row. Repeat these 2 rows until 16 loops on the needle (ending on a purl row). (1.5")

Change colors.
Work Middle Segment (Bottom/Top of foot):
K across; P across. Repeat these 2 rows until you measure 6".

Change  colors.
Repeat Heel/Toe pattern (this part will be your toe) (3" total)

Change colors.
Repeat Middle Segment pattern (this will be the top of the foot). (6")

Ankle (same color as bottom/top):
K across, cast on 8 additional stitches.
P across, cast on 8 additional stitches.  (32 loops on needle)
K across; P across. Repeat these 2 rows until 2 1/2" from first ankle row.

Work Cuff-ribbing (same color as ankle):
K2, P2 across; P2, K2 across. Repeat these 2 rows until cuff is 1.5".

Use crochet hook to bind off.

Sewing Guide:
Sew into a sock shape. I found that sewing from the wrong side (purl side) made a nicer look on the outside, but it doesn't really matter.

Sew the sides of the Ribbing and cuff together to make a tube.

First heel/toe (end of sock) is the heel. Sew bottom of two long ends of cuff to the heel end of the sock (that's the back of the foot).

Sew the top and bottom of foot together.

Sew the increase/decrease edges of the toe together.

Sew the increase/decrease edges of the heel together.

I recommend reinforcing along the place where the heel triangle tips meet the inside corner of the cuff. When you put the sock on, if you see gaps there, that's where you need it.  That will be where the most stress from stretching occurs.
