I want to make the Astrodome hat from Knitty, but I’m not quite sure what weight of yarn to use. The hat in the pic is knit with Goddess Yarns Julia. The gauge on the hat is 16sts/24rows = 4" (the gauge for the matching scarf is 14sts/16rows = 4").
Does anyone know what weight of yarn I should shop for? Thanks a bunch.
