The Craft Yarn Council’s Standard Yarn Weight System. Gauges are stitches per 4 in (10 cm): knit in stockinette, crochet in single crochet (lace in double crochet). CYC calls them guidelines: your pattern’s gauge comes first.
Project yardage is an estimate from the StitchTick yarn calculator (single crochet and stockinette); your stitch and tension change it.
