The 98-point- Sizzle hat pattern is a play on words for 98.6 F, the “normal” body temperature. This pattern includes instructions for 2 weights of yarn, bulky or worsted which will knit up in 2 different sizes;
20”/ 51cm x 10”/25cm in bulky weight
OR
22”/56cm x 10”/25cm in worsted weight
keep in mind that not all bulky yarns will reach the same gauge and may create a different size hat if vastly different. This pattern is great for using up small amounts of leftovers from other projects, but could easily be worked in just 2 colors. Changing needle size can create different sized hats.
