his cute hat, I made for my granddaughter, which led me to create it for my customers in adult sizes, as shown in the pictures, with matching earrings. This set of instructions is for the youth size and can be adjusted to adults. Good Luck with your caps and I hope you'll give feedback on your own caps if you should choose to make this cap. Happy Crocheting!! Pattern from leisure arts which I adapted for youth.
