Knitting for baby

Swank is moving along nicely (I've done the back and fronts and will be attacking the sleeves shortly), but I've had to put this project on pause because I've got a little baby knitting to do.

Friends of mine just had a lovely baby boy and now that I know the sex, I'm throwing myself on the needles for some marathon baby knitting.



I've chosen Aran Pullover from Knitting for Baby by Melanie Falick and Kristin Nicholas (a really lovely book).

I hope mine turns out as nice as this one.

My only concern is that the baby is of Scottish heritage, yet the sweater is an Aran design, which hails from Ireland. Plus I'm knitting this thing in green. Am I committing a HUGE cultural faux pas with this thing? What do you think?
