Olives Christmas Hat

Olive’s Christmas Hat is worked in stockinette stitch in the round from the top down. Depending on your preferred look, it is worked using either 1 strand Merino + 1 strand Soft Silk Mohair held together or with 2 strands of Merino held together.
The hat is finished with a ribbed brim and Italian bind-off method to make sure the edge is perfectly neat and elastic. The tassel is made last and sewed onto the hat as the final step.
