That One Skein Chunky Hat deserves its name !
This quick one skein project is worked in the round and can be crocheted in less than two hours.

The variegated yarn I used gives it its unique casual look, but it can just as well be worked in a plain color yarn that will showcase its two textured stitches.

That One Skein Chunky Hat comes in 5 sizes (Craft Yarn Council of America’s standard sizing), to fit head circumferences:
baby (B) 35.5 cm/14”.
toddler (T) 40.5 cm/16”
child (C) 45.5 cm/18”,
woman (W) 50.5 cm/20”,
man (M) 56 cm/22”.

That one skein chunky hat is great for a fitted look, but if you want to wear it as a slouchy, just add 3 more rounds in pattern stitch.
Please note that one skein of Katia Inca is 100 grams, and the yardage is 109 yards.
