My Perfect Sweater

I signed up for the online class with Ysolda Teague through the Squam Arts Center. Hoping to learn how to knit a sweater that really fits.  I thought my Romy was going to fit well, but it is far from perfect. I think I made the armhole openings too long, that seem to make it all pull, and I'm constantly tugging at it. Might not have been the right yarn either.  Anyway, looking forward to the class.
