I finished Adam's vest. This is my own improvised design, but based heavily on the Noro vest I made for myself, which in turn was based on the Rowan Summer Tweed pattern: Rosemary.
The yarn is Cascade 220 Paints in Colour 9926. Its left over from the yarn I bought for Nigel's Retrofit jacket. I used about 3 skeins for this vest. I knitted it on 5mm needles and it's based on a 60 stitch cast-on with a single 8 stitch cable up the front. I extended the cable around the back of the neck for a neater finish.
