Her head measured 21 inches so I cut two 11 1/2 in. by 8 1/2 inch squares of purple and two 11 1/2 in. by 3 in. for the trim. The pom-pom top I stayed close to the same measurements on her blog.
And then I decided to make her a matching scarf since I had enough left over:This isn't anything new, but I finally made one. Super easy....two long strips, sew them together down the center and cut 1 inch apart into the scarf coming to 1/4 inch of the seam.
