This is a slightly modified version of my tulip hat pattern. For summer, I didn’t want to flatten my hair so I made the previous version a little loose on my head. Also, I was trying to mimic the silhouette of poplar bucket hats. On this second version, I made the head circumference slightly smaller, and the crown slightly rounder.
The pattern includes 1/4” seam allowance (shaded area). If you print it on 100% scale, the complete hat should snugly fit 22 1/2” (57cm) head. When printing, scale up or down to fit your head :)
