Hat Done.

Hat done, washed, and blocked. Not photographed yet, but hey at least I've gotten this far.

Washed in hot water, yes, HOT,  with Soak no rinse wool wash, and a splash of white vinegar. I let it sit for at least an hour or more, depending upon when I remember to pull it out of the water.

Gently squeeze the water out, smoosh in a towel to remove more water and stick it on a clean towel on the radiator to dry.
