This is a very special kind of hat pattern with infinite possibilities.
Have you ever read one of those make-your-own endings books? This hat pattern is inspired by the freedom of choice! Instructions are provided for several varieties of brims body shapes, and crown decreases. You’ll follow along choosing between ribbed, rolled, or seed stitch brim, then choose beanie, beret or slouchy body style, and finish with a beanie, ruched, stocking or beret crown. Do it different, every time.
As part of the Math for Hats book, this pattern also has notes along each step connecting it to other pieces of the book to help you understand all the components of the pattern including how the gauge is used in sizing, how yardage is calculated, how the decreasing produces each crown shaping option, how repeats match up, etc.
