Thanks for the advice. Actually, I went one half size smaller and the swatch is pretty much dead on. And I'm sure that I'll grow considerably by the time I'm done, I don't mind it being a little big. Plus the pattern says it has quite a bit of stretch, so it'll be hard to fit during construction anyway.
Here's the link to the Interweave photos for that issue. The pic is about halfway down the page.
I'll keeping posting as I go.
