The tweed vest is finished and blocked.
I am 95% happy with it. Here is the 5% getting in the way of pure satisfaction:
In spite of my best efforts, I failed to have the line of full-fashioned decreases around the v-neck look identical on both sides. I am not sure how to fix this in the future; this time around, I made sure to ignore the slip-stitch pattern and to knit the two edge-stitches on each row, in order to have a firm edge from which to pick up stitches afterwards. I also made my decreases in stockinette, obviously. And I used the same picking-up technique as I always do, on both sides. But I probably should have kept an extra stitch for a stockinette selvedge on the right-side front. Must remember to try this next time around.
Otherwise, this has been an all-around happy project. A side-benefit of using a slip-stitch pattern is that the fabric is a bit denser (although quite flexible and cushy) and therefore warmer.
The specs: I used three skeins of OnLine Tessa wool that had been living in my stash for about five or six years, along with two skeins of Cascade 22o Heathers in grey. That second skein of Cascade was only needed for the last few rows of the body as well as the trim, so my guess is that one could squeeze a size 8 vest like this one out of 250 yards each of two worsted-weight yarns, plus another 50 yards of one color or so for the v-neck and armhole bands. As I mentioned in my previous post, the slip-stitch pattern is described in Barbara Walker's Second Treasury as "Woven Tweed" and is very easy to execute in the round. The only change required in that case is to cast on an even number of stitches, instead of an odd number. Piece of cake!
And now for something a bit wilder, just so you know my knitting basket hasn't been totally overtaken by tweedy grey-ness:
So wild, so pink, so blood-orangey! and did I mention utterly addictive? This one I'll just have to keep for myself.
