That's great! I'm a bit intimidated by going to one of those as I'm still not very good.
Yes, they'll probably sneer at you cruelly and kick you out! Seriously, you should go to a knitting group! People go there because they want to share their craft, so it's usually a supportive atmosphere for a beginner. (And if it isn't, those people suck and aren't worth your time.) Have fun at your knitting circle!
I have some of that yarn but only 2 balls, how many did yours take?
Less than one of each color, actually, and I made size large (which was a mistake, but I successfully shrank them a little in the dryer). The pattern instructions say you'll need 2 50g balls of each color, but I had enough of the contrast color left over to use as the contract color on some endpaper mitts, and I have tons of the MC left over too.
