A warm wool hat with a pickleball motif. A bright ball is a must for pickleball, but other than that you could choose any other colors to make this charted pattern. I used Knit Picks Palette fingering weight yarns in these colors:

MC1 - Asphalt Heather 80 yds
MC2 - Larch Heather 25 yds
MC3 - Abyss Heather 11 yds
CC1 - Canary 20 yds
CC2 - Lichen 20 yds
CC3 - Tarragon 15yds

The hat is made with a 2X2 ribbing to start then you go into the colorwork reading from the chart.
