Knitting Zen

I didn't get much knitting done this weekend. Okay, I didn't get any knitting done this weekend. Most of my creative energy is going into my NaNoWriMo novel. (Here, if you want to peek.) However, I did just now try on the sock and take a picture:

It fits, but it sort of fits exactly, i.e., there' s no stretching involved to get it on. I guess it's better to be bigger than smaller, but it seems like it will stretch out a lot. What about shrinking? Does anyone have any experience with washing Fixation? Does it shrink at all? Am I worrying needlessly? Should I finish this one and go ahead and make another one just like it, or what? Should I (gasp) rip it out again and start over? Should I (I'm guessing this is what I should, and probably will, do) make a sock using a pattern specifically for Fixation? Does it make a difference? So many questions . . .
