Thanks. Those are the finished sizes, and 43" only gives 1 1/2 inches of ease, so maybe I'll go with the Large - 46". which is 4 1/2" of ease. I'll do a swatch first with Size 6 (recommended) needles and then Size 5. If the Size 5s make it just a wee bit smaller, maybe I'll go with those. I also thought about doing a cable in the front only with Size 6 needles, which would pull it in a bit, but then the back might be too large. I'm not used to making sweaters or vests. I'm trying to expand my knitting repertoire!
