This is a free add-on Santa hat that fits some of my patterns including my bobas, hipster hamster, and peppermint mocha deer. It just needs to be made using the same yarn type and hook used for the main body of the ami.

My Santa Hat made with bernat blanket yarn and an 8 mm hook is about 3.5 x 3.5 inches.

Supplies Required:
Scrap amount of red & white yarn
Hook size that matches the type of yarn you choose
Yarn needle

What I use:
Bernat Blanket & 8 mm hook
Premier Parfait Chunky & 5 mm hook
Worsted weight acrylic/Bernat Baby Velvet & 4 mm hook
