I, on the other hand, try to avoid too much seaming and sewing, having never learned how to sew, so I do as much in the round as I can.
So -- I did it. I put the stitches on waste yarn, tried it on, and put them back. It was the most nerve-wracking, tedious thing I've ever done, and I will never do it again!! I'm sure it didn't help that I am knitting with sport weight dark blue yarn and used black sock yarn for the waste yarn but woooooaaahhh! That was hard. There has got to be a better way. I will definitely try some 60" circs next time (once I get some of those).
I am afraid to put more than one fixed circular together to try it on because I'm sure something will fall out and I'll drop stitches.
This sweater is just going to have to fit without me trying it on again!
The one good thing in all of this is that I finally finished the sock I was working on. It only took 2 1/2 years........
