`I think you will have more that enough. If anybody has made the bigger size maybe they could let you know how much yarn they used. the increase in yardage seems way to much for a couple of inches.
somebody did the CPH in size 44 using 12 skeins of the summer tweed that I am using. so I would think 20 odd would be plenty.
Love the colour that you bought, isn't it great when you get a bargain. got my yarn at a half price sale.
