This is the matching doll hat pattern for the children’s size hat that you can find here:

This hat is worked from the bottom up with a flexible bottom edge that continues in the round until you complete the hat with a crab stitch upper edge. This hat is form fitting and is a hat style vs. my looser topped Unforgettable Convertible Beanie pattern. You can find the looser beanie style hat here:
