While the end result resembles basket-woven strips of knitted fabric, the actual material comprises interconnected squares in two different orientations.

Originally, this pattern called for handspun, and if that's chosen- it would be yarn between 15 and 18 wraps per inch and approximately 106 yards (97m) per ounce (28g)
