I am making my uncle some hunting socks. He wants them wool and very thick. I showed him some socks I made with worsted weight yarn and he thought they were close but not quite thick enough. Anyway, I found a pattern for very warm thick wool socks that has you using two strands of worsted weight yarn. I was a bit concerned they'd be TOO thick, but so far (I've done about 4 inches of the cuff) they seem to be good. My biggest problem is the cast on. I've cast on three or four times trying to get it looser but it still seems too tight to me. These are going to be quite high on the calf, they need to go over the top of his boots and fold down. In fact it's okay if they are a bit too loose because the boots will hold them up. They are going to be taller than the ones the pattern makes which is probably the issue. The pattern had me cast on 32 stitches. Looking at other sock patterns they always cast on AT LEAST 50 sts, but those are worsted weight yarn patterns, this one is chunkier, and it's using size 7 needles which is larger than other sock patterns.
What would you do in this situation? I'm pretty new to knitting so fudging with patterns too much isn't really my forte. Would you cast on more sts (how many?). Then would you decrease back to 32 after the cast on or stick with the cast on number for the whole leg (as they do in the pattern)?
A large part of me is tempted to go with a new pattern altogether (namely this one: http://www.ravelry.com/patterns/library/hunting-socks ) except that he did want them thicker than worsted weight. But they are hunting socks so the height should be where he wants them so they are likely large enough around for that part of the calf. Is there anyway to easily modify this pattern for the double stranded worsted weight yarn?
