How long should a cowl be to wrap twice?
Try 12–24 inches for a single-wrap cowl and 8–12 inches for a longer cowl. The cowl should be at least 18 inches tall if you want to wear it as a snood.
How many stitches should you cast on for a cowl?
To find out how many stitches to cast on, multiply the stitches per inch by the desired width of the cowl. For example, if your gauge is 2 stitches per inch and you would like your cowl to be 23 inches wide, then multiply 2 by 23 to get a total of 46 stitches to cast on.
