As of January 2025, this pattern includes instructions for how to knit the hat in any gauge using any yarn. For heavier yarns (DK and thicker), more than one skein may be needed.

This is far from the first hat of this style, but none of the existing patterns for a seamless, one-piece, double-thickness hat that I found had the swirl-style crown that I usually use. So I found a way to mimic the swirl decreases in a top-down crown, and to make things a bit less fussy to start, I combined a few techniques to create an inside-out cast-on that requires no waste yarn or crochet hook and looks virtually identical to the finish for a bottom-up hat.

• This hat is designed to use all of a single skein of yarn. To maximize your yarn usage, a kitchen or jeweler’s scale is used to determine when to start decreasing.
• A photo tutorial is included for the cast-on method recommended in the pattern.
