My sister got an I-Owe-You for Christmas knits, and I let her choose between the dog sweater I was originally planning to make and the giant cowl I told her I didn’t have time to knit before Christmas. She chose the giant cowl, and I started it as soon as I could. I cast on a bunch of stitches using HiKoo Kenzie yarn held double, and then I just k1tbl, p1 around and around. I went through four skeins of yarn before I decided it was big enough. I think it ended up just right because it’s quite dramatic but not too deep to comfortably loop around your neck twice.
