This creation is meant to be worn purl side out, for extra smoothness against the scalp.

Since knitting is easier for most than purling, the hat is worked knit-side out, ends are woven in on the knit side, then it is flipped purl-side out for wearing.

Version shown is sized large for a generous, gentle fit.
-If you prefer to have a snug fit the hat COULD be worked on smaller needles, but I think a tighter stitch would detract from the soft feel of the fabric.
-I think a better, much softer solution would be to knit with the given stitch counts, then if necessary felt your hat slightly to closely fit the intended head. If you are using an easy-care fiber and wish to have a relatively snug fit, knit one size smaller than you would normally, or use a smaller needle. Stitch counts for alternative sizes are indicated as Large(Average/Small).
