I'd love to be zen and worry less, but I need to give this some forethought so I don't spend a lot of time on something, only to have it fail in the end. I don't know what I'm doing at this point, so I inevitably come here to seek help from the veteran knitters!
One dumb question: how do you know that the sleeves will fit into the armholes? Wouldn't you have to match it stitch for stitch? The patterns say to cast on a specific number of stitches, but the armholes are just x number of inches. Does this just normally work out?
I need the stuff that the pattern doesn't tell specifically since they all assume that the knitter actually knows things, which I don't!
