Pithy instructions: hand dyed DK weight, knit in the round, 1x1 rib for 1” brim, switch to bigger needles and hold the yarn doubled , knit till long enough, decrease rapidly & bind off, add a pom-pom (if you’re into that sort of thing).
And this!
Pithy instructions: 2 strands sport weight (different colors) held together or marled dk weight.
