Gauge is not super crucial with this pattern - the ribbed body section stretches to fit most. Any worsted weight yarn is suitable, wool and wool blends work best, and acrylic works well. You will need 150 yards of the main color, and 100 yards of a contrast color.
The body is worked flat then seamed, and the cuffs and edging are worked in the round. A quick project, most crocheters will be able to complete a pair in one evening, within 3 hours.
