This is a recipe for yarns from DK-Aran weight. Yardage requirements are determined by your gauge swatch, but my best guess is that you’ll need 6-10 ounces, depending on the size you’re planning to make.

V.1 was the tester version.
V.2 is a great deal more thorough, but how to best graft the crotch is still in testing phases - please watch careful for v.3!
