I'm starting the Altostratus cardigan using Malabrigo sock. The pattern gauge is 4 sts. per inch on 8s. I'm getting about 5.5 on 9s and about 5 on 10s. I don't get 4 until I go all the way up to 11. The sweater is all garter stitch and I'm concerned that if I use 11 it will be too stretchy and sloppy looking. It's a pretty stretchy sweater anyway and the pattern recommends making a size 2-3 inches smaller than what you would normally wear. If I stick with size 9 needles I don't know whether I should still make the smaller size or my actual size. I don't know how much difference 1.5 sts will make overall.
