This pattern was inspired by and designed for my dear friend Katie. Katiebird is her childhood nickname, and I thought it was the perfect name for this design. Katie is colorful and fun and loves to laugh, so I wanted to design her a whimsical hat that will go with everything! She loved the idea of puff stitches, so I turned them into feather-like sections inspired by her nickname.
