The Amazing Fit Anyone Hat
This hat is AMAZING because it fits ANYONE.
All decreases are worked in measurements of 10 stitches. To make a larger or smaller hat, simply cast on more/fewer stitches in multiples of 10 (every 10 stitches alters the size of the hat by about 3 inches). Recommendations: cast on 70 stitches for adult male, 50 stitches for child size. The 60 stitch cast-on in the pattern is for the average adult female head.
Instructions include options for a garter stitch or basketweave brim, but I’m sure you can come up with something more inventive than that!
The corresponding blog post explains how to adjust gauge to transfer the the “10 stitch decrease” logic to any yarn/needle size, so you can make the hat in any yarn you like.
