Any Worsted weight cotton in two contrasting colors could be used. Yardage not given, but presumably less than one skein of each color. Pattern can be enlarged or shrunk by casting on different number of stitches.

From pattern notes: “Based on the traditional Tumbling Blocks quilt pattern, this easy to knit cloth appears to look like a 3D cube!”
