Choose your needle, based on how you knit, if you knit loosely , use a smaller size needle, and if you knit tightly use the larger size needle.

You will need at least 2 colors of sport weight yarns.
For the longer hat I used Malabrigo Arroyo in Black and Knit Picks Chroma fingering, in the color Prism.
For the small hat I used Dream in color, Smooshy, Black in the background and 5 different contrasting colors.

Smaller hat takes about 70 grams total of yarn
and the larger one takes about 130 grams of yarn.
