Need yardage for Picot Swirl Cloth pattern

I need help please. I want to start knitting the Picot Swirl Cloth pattern: ( ) but need to know the required yarn yardage that is not stated in the pattern. If you know or have knit this pattern, I would appreciate receiving the information. Thank you.

With most solid color 2½ oz balls of kitchen cotton (sugar or peaches and cream) you should be able to get 2 washcloths out of it. The multi colors have less yardage so you’d only be able to get one large one or 1½ regular ones out of it. Just start with a ball of it and you’ll have some leftover.
