1. Using a size 4 mm 32" circ (one size smaller needle than that used for the body), and starting at the bottom of the right front, pick up sts along the right front band, around the collar, and down the left front band. Do so using the same ratios I presented earlier:
- for vertical sections (front bands and the upper V-neck), pick up 3 sts for every 4 rows,
- for diagonal bits (the V-neck and the short slopes on either side of the back neck) pick up one st for every row,
- in the tiny gaps between the back neck slopes and the centre back neck, work M1s into the horizontal strand in the gap; make the M1s lean toward the centre back neck, i.e. M1L on the right hand side, and M1R on the left hand side.
2. Knit one row. Insert locking st markers where you want your buttonholes to be. The top one should be 3 stitches below the V-neck, and I like the bottom one to be about an inch from the bottom. Space the others accordingly. Place them BETWEEN the two stitches where you want each buttonhole to go. Use locking stitch markers of a different colour to mark where the V-neck begins and ends.
3. Buttonhole row AND beginning of short rows for collar(RS): *Knit to 2 sts before buttonhole marker, k2tog, YO, k2tog, rep from * until last buttonhole is completed, knit around collar to 2 sts before left side V-neck marker (the second one), SWR (see below), turn.
4. (WS row): Knit to 2 sts before right side V-neck marker, SWR, turn.
5. Knit to 4 sts before left side V-neck marker, SWR, turn.
6. Knit to 4 sts before right side V-neck marker, SWR, turn.
7. Knit to 6 sts before left side V-neck marker, SWR, turn.
8. Knit to 6 sts before right side V-neck marker, SWR, turn.
Cont to work pairs of short rows, working the wraps 2 sts apart until there are 22 wraps on ea side in total (total desired number of garter st ridges minus 3). In this case, I wanted 25 ridges in total (remember that in garter st, it takes 2 rows to make one ridge.)
AT SAME TIME, after 12 ridges (about half the total desired number of ridges) counted from the RS of the waistcoat back (don't count the first ridge which is actually the ridge from Row 8 of the charted pattern), inc approx 3" worth of sts (14 in this example) by the kfb method in the centre back between the shoulders. The increase row must be worked on the side that will become the RS when the collar is flipped over into its position when worn.
After the last SWR and turn, knit to end, ignoring wraps, i.e. don't bother to neaten them (see note below).
Next Row (WS): Knit to end, ignoring wraps, and working (k1, p1) into each YO to complete the buttonholes.
Last Row: Knit.
BO knitwise from the WS, using a 4 mm dpn in your right hand for the front borders (which should be worked rather firmly) and a 5 mm dpn (one size larger needle than for the body) for the collar (which needs to be done in a more relaxed manner). When casting off, work the last 2 sts tog for a neat corner.
General notes on garter stitch short rows: I've used Lucy Neatby's abbreviation SWR for slip, wrap, replace. Slip next st purlwise, bring yarn to opposite side of work, replace the slipped st, turn, and continue. Make the wraps fairly snug. In fact, Lucy talks about "strangling" the wrapped stitch! In garter st there is no need to to do anything more to neaten the wraps. Neither should you slip the first st of the next row as you would do in stocking stitch.
So, here's what the completed deeper shawl collar looks like:
Beautiful fall morning here, but...
chilly. Winter is coming!
P.S. In the course of re-knitting the waistcoat, I uncovered an error in the upper back regarding the placement of the knot pattern. See here for the correct numbers.
