Knit into the back of the knit stitches and then purl. I work in knit one, purl one as it makes a tighter rib.
Change to larger needles and knit three rounds.
To start pattern:
4th round: ‘knit 3sts. Thrum 1" as follows
Insert right needle through the st below the 1st st on the left needle, place a 4" piece of roving (pulled and twisted) over the right needle and pull it through to the front, then knit the st on the needle. Pass the thrum up and over this st. Repeat from “to” across round.
Knit next 4 rounds
9th round: knit 1 st “thrum the next st, knit next 3 sts” repeat” to “ across round. Knit next 4 rounds. Repeat rounds 4 to 14 in this fashion until the l desired length. In my case it is 8.5 inches from beg.
To Make Heel:
I do not put the thrum stitches in the heel as I feel it would make it more difficult to put work boots on, but you most certainly can if knitting for snow boots.
Divide stitches in half (24sts) and work back and forth on one needle , turning work at the end of each row.
Working on these 24 stitches only work flap as follows:Row 1: *slip one, knit one* repeat across row.Row 2: slip one purl across.
Repeat until heel flap measures 2.5 inches or desired depth.
End with purl side facing.
Slip one, purl 12, purl 2 together, purl one, turn.Slip one, knit 3, knit 2 together, knit one, turn.Slip one, purl 4, purl 2 together, purl one, turn.Repeat until you have 16 stitches on needle.
With same needle continue and pick up and knit 12 stitches down the right side of heel, work across the stitches on the front needle, pick up and knit 12 stitches on the left side of the heel.
Needle one - left side of center heel - knit to within last three stitches of end of needle, knit two together, knit one.Knit across center needle.On next needle knit one, slip one, knit one, pass slipped stitch over, knit to end of needle.Next round knit even.
Repeat the above decreases until you have 48 stitches remaining.Distribute on needles as follows: (16-16-16)Knit three rounds, start thrummed round.Repeat for desired length or in my case 6.5 inches.
Needle one: Work to within last three stitches, knit two together, knit one.Needle two: knit one , slip one, knit one, pass slip stitch over, knit to within last three stitches, knit two together, knit one.Needle three: knit one, slip one, knit one, pass slip stitch over.Round 2: Knit even.Repeat above until you have 24 stitches remaining. Leave 12 inch length of wool for grafting.
Place 12 stitches on each of two needles. Using a wool or darning needle *place needle into first stitch on front needle as if to knit and slip off needle, put needle in next stitch on needle as if to purl and leave on needle, let yarn go under the first needle and working on the back needle, insert needle into first stitch on back needle as if to purl and remove from needle, insert needle into next stitch as if to knit and leave on needle.* Go under the needles and back to the front and repeat from * to * until you have one stitch left and secure in place.
The thrummed socks are time intensive but well worth the effort. They are wonderful knit as slippers as well; just make the slipper top shorter.
Have fun and enjoy.
