I designed this to be very fitted so the mister could wear it for cycling. The body and sleeves are extra long, so no skin sticks out when he is bent over with his arms stretched out. It worked out really well! This garment only comes in one size. It should be quite easy to change the size a bit, if you’d like. Shorten or lengthen the body and arms as you see fit. If you need a bigger chest, adding purl stitches between the cables should help.
This yarn is discontinued. Recommended gauge for it is 3 3/4 sts per 1 inch. Nice subs would be Rowan Cork, Scottish Tweed Chunky (exact same yardage and everything!), Blackberry Ridge Woollen Mills’ bulky weight two ply wools, or Bartlettyarns’ 3 ply. Mainly, I’d suggest a yarn with at least two plies that’s woollen spun so that it’s a light and lofty yarn, which will make a sweater that doesn’t weigh so much.
