The Daxette is the fingering weight version of the Dax hat!
As written it fits a 21 inch head, it is very easy to change the circumference by adding/subtracting stitches. Directions are included in the pattern. Also easy to make it as slouchy (or not) as you like!

Any fingering weight yarn will work, about 200 yards.
you will need US#2 and #3 16 inch circular needles and US#3 DPN’s for the crown.
