The clearance yarn I got was close to the right gauge but a little different - it advises 3 sts per inch compared to the pattern's 2 sts per inch (size 11 needles). I think its normal chunky weight and the grams per yard was definitely less (0.9 g/yd versus 1.2 g/yd for the Bohemian). The brand is Classice Elite Yarns "TwoTwo", 100% highland wool (not sure what "highland" is).
I called the big yarn store (Pasttimes in Auburn) where I got the yarn to ask about converting the yarn, and they said that using a different weight of yarn is no problem, as long as the pattern gauge was followed. The person said to always convert by yardage, not grams (weight) to find out how much of the other yarn to get. I just think this means I'll probably have to use different size needles (bigger?).
I don't know from experience, since its my first big pattern
, but i'd guess that you shouldn't worry about the size of the yarn too much, as long as its not a really big difference :?: .
Knit-alongs are sooo cool!!
