Chunky & Bulky
Thick yarn works up fast, it's easy to see your stitches, and makes for really gratifying projects.
Chunky yarn is usually about 110 yards/ 100g, to be knit on size 10 - 11.
Bulky yarn covers a range of options, and is usually twice as thick (half as long) as chunky yarns, but there is a huge variation in this category. Needles range from size 13-19!
