Fits from 39 ½ to 46. This is a very fast sweater to knit, using 3 strands held together of worsted weight yarns! Use all the same color, or vary with 3 different colors as we did, for a tweed effect. Work goes very quickly with the 3 yarns, and knitting needles, US # 13 and # 15. They will fly off your fingers fast! IT is a very warm sweater, and the V neck shaping is good to wear with many different types of blouses, shirts and tops. Have one ready for the cold weather!
