The Pattern does not give any gauge information, and since this is a felted hat, perhaps it is not so critical. I purchased this as a kit from Wool Gatherers, LLC, at Stitches Midwest; however, I don’t see it available on their website, which is www.wool-gatherers.com, any longer. Too bad - this is a great hat. Fiesta calls Kokopelli a “heavy worsted.” This hat can be made without the called for Heaven yarn. I did not use it.
