Embellishing a pilot's cap with felt hearts helps keep tiny ears toasty. Cut two large hearts from felt. Then use a needle and thread to stitch them to the cap at three points. If you want the decoration to be permanent, affix hearts with fabric glue before sewing.
This project can be completed using a store-bought pillow cover, but a flat piece of fabric works best, as it fits easily into a sewing machine. After you embellish the fabric with leaf patterns, you can use it to make a pillow cover.
