Introducing Tessella. A hat designed with versatility, style, great fit and usability in mind. The band is reversible so you can fold and wear the hat as a beanie. Tessella wears wonderfully all year round. I'm right now in the process of making my 5th Tessella. I have gifted this hat to loved ones all the way from age 3 to age 83 and they all LOVE IT! Pattern offers instructions for sizes; small 18", medium, 20" & large 22". Adjustments can be easily made to allow for a snugger or looser fit or to add more slouch to the hat. There are two methods for decreasing the hat. "My preferred method" and a second alternate, possibly simpler method. You choose!
