Three different scarves are included in the pattern.
These Scarves are all made using similar patterns. All scarves are worked using the same number of rows, with increases.

The difference between Scarf A and B is their length, because the number of sts cast on is different for each.

Scarf B and C are the same length, but Scarf B is made with one kind of yarn and worked all Stockinette stitch, and Scarf C is made with two kind of yarns and worked in a Garter stitch & Stockinette stitch combination.
