This is a PDF sewing pattern from MadeByMePatterns with color step-by-step instructions. You can print it with layers. Stitching lines are diagrammed right on to the photos so you never need to guess where to sew. You do not need a serger for this pattern. The pattern includes sizes from infant to adult size (head circumference from 15.7in (40cm) up to 23.7in (60cm)). This pattern is for sewing a very cozy and warm hat for all ages that covers the ears, keeping the wind out, and offers shade from the sun with the brim at the front. Secure this hat with a simple snap under the chin.
