Fiesta Hat is so colorful it will add some brightness to your winter months! It is made with soft acrylic yarn. I use two types of yarn, the red is a thicker yarn and the multi color is a thinner yarn. Using the two different types of yarn, makes the hat softer and more stretchable. One size fits most. The hat measures 10" with a 1 1/2" brim and the circumference is approximately 19" but it will stretch!Add some color to your life with this bright Fiesta Hat!
