Since I live in New York City, I tend to think about heavier winterwear for holiday gifts. For the past few years, my sister has been living in the South (first in New Orleans and now in Houston), so I’ve had to think about gifts that might be a little lighter, like today’s summer slouchy hat crochet pattern.

This post contains affiliate links. I may receive compensation (at no added cost to you) if you make a purchase using these links. Yarn for the sample was generously provided by Cascade Yarns.

This airy slouchy hat is perfect for transitional weather, or as a gift for a loved one living in a warmer clime.

It combines a slightly open stitch pattern with a cotton blend yarn, Cascade Yarns Avalon. The construction is also a bit unusual, but I think you’ll enjoy it!
