Every season, I try to introduce a different stitch to my designs.  I have this book from the library with some interesting stitches.  I chose the Ripple 1 stitch  to design this  creamy 100% merino wool.  I learn to do a new way to create a chain and this hat is designed from brim to crown.  It fits a 21 1/2 to 22 1/2 inches head.  Measure around your forehead toward the nape.  One of a color.
