I made these two hats last month, in September. I am super pleased with how they turned out! I used the free pattern MS Slouch by Woolly Wormhead.
I made them using the smaller size, as they are intended to be used as chemo hats. The pattern is written for four sizes (17 inch to 23 inch).
Since they are made using the seed stitch, they took a bit longer than usual for me to make. Seed stitch is simple, but (for me at least) alternating every stitch between knit and purl slows me down, lol. But it’s so repetitive you don’t need to constantly look at the pattern, just keep track of your length until you get to the crown.
