Knitty Blackberry
So, I'm knitting knitty.com's Blackberry and it's for my somebody who's a bigger size than me. I'm not used to making bigger sizes or anything and I'm knitting the XL size. I just realized her arm circumference was probably a lot bigger than the one in the pattern and was wondering if anybody could give me hints on what I should do to get a bigger arm shaping perhaps? Or maybe it'll stretch and fit after all? I'm not really too sure. I just don't wanna knit something too small and have it not fit at all. Thanks!
