The Humdrum Beret is a pattern for all ages, yarns, and hooks. You can make it as big or as small as you like!

I’ve tested it with Homespun and Simply Soft.
For a warmer, looser beret, use the Homespun and a 6.50 MM hook.
For a more structured, shiny look and feel, use the Simply soft and a 5.50 MM hook.

As of a few weeks ago, I changed the pattern to give it a border. It should stay on your head better.
