I am not as happy with this version.
I used front and back post double crochet stitches for the ear warmer portion, and also reduced to row lengths to create a more curved shape. I think I should have done a couple of rows without decreasing first, to make it wider. It dies cover the ears well enough, though, and curls more snuggly around them, which would reduce drafts.
I think I will play around with other stitch patterns, too. The goal is to make the portion over the ears dense and well insulating.
