I love knitting seamless sweaters. You mindlessly knit the body around and around. Ditto for the sleeves. Join it all up. Decrease, decrease. Voila! Sweater! But I've never knit a seamless set-in sleeve. Lamour, which I am knitting in the round from a pattern written for knitting in pieces, has set-in sleeves. So I started fretting after about 2" of the body had been knit about how to deal with the sleeves and yoke. I could knit the whole body, splitting when I get to the armholes, then knit the sleeves and sew them in. But would I knit the sleeves in the round or flat? Will that be a pain stitching sleeves into a yoke with sewn shoulder seams? Should I knit it seamlessly? Will that be hard? Will there be problems down the road that I'm just not seeing yet? Fret, fret, fret. And then there's the measuring. The pattern, like most lace, needs a severe blocking.
So when the pattern says knit for 35cm, I--after a quick check on Google to see what 35cm is in inches--just don't know how stretched out the lace should be when I measure it. More fretting. First I think, better to err on the long side but then I worry that I'll run out of yarn. Stretch it this much? This much? I just don't know. Since I am quickly approaching the 35cm mark (stretched) I really need to get a grip on myself quickly and figure out what my next steps will be.
