I envy my fingers – unlike me they remember things so well! Once I got started with the pattern it was almost like typing, and a favourite movie helped making this a quick knit: Woody Allen's Match Point is so compelling (even the the third time) I knitted faster than usual.
Short notes about the construction:
1. Knitted in one piece until I reached the armholes, then divided into three sections.
2. Armholes shaped using short rows.
3. Back and front joined using a three-needle bind-off and knitting a neck gusset (which I learnt from Alice Starmore's Fishermen's Sweaters). Picture here.
4. Stitches picked up around the armholes for a garter-stitch edging.
5. I picked up stitches along front; then knitted gusset stitches, back stitches and gusset stitches; then picked up stitches along other front. All stitches knitted back and forth for garter stitch edging.
My mother seems pleased with how her new vest turned out!
