Well, the sweater is done, except for blocking! It is rather close fitting (but wearable) , and I hope it will expand a bit after a wash and some careful stretching.
What have I learned? The importance of swatching, for one thing, but more significantly, the importance of adding enough ease when designing a garment. I wound up casting on 128 stitches for the body, and probably should have cast on 135 instead and then increased up to 150. Lesson learned for the next one... which I am already dreaming about.
I want to do another seamless one with colorwork, but this time done in more earthtones with raglan shoulders. I am still not sure about what design to use. I thought about doing a Celtic frieze motif running all the way around under the armholes, but I'll play around to see what it looks like. I also have come up with some possible designs based off of the Rovaniemi mittens using the same technique. So many possibilities...!
In other knitting news, I taught myself the Mobius cast-on yesterday and did a practice piece. The cast-on is incredibly quick once you get the hang of it. I am looking forward to using it in a real project!'
