The yarns I have used are Jo Sharp Classic DK wool, 507 Miro, and Heirloom Celtic, 927, an Alpaca and Merino blend. The tail is an extended i-cord, with 2 additional i-cords grafted near the end. The tassel finish is rounded out with short strands of wool knotted through individual stitches along the i cord.
The stretchy rib makes the hat fit nicely on a range of head sizes, but also allows the hat to be worn with the brim turned up or down as desired.
