This kit gives you everything you need to make a winter cap from the free pattern posted under the "projects" tag of the "News" page. It contains enough fabric to make one hat with double-thick earflaps, plus enough heavy craft interfacing for 1-2 hat brims and elastic for up to two hats.
Unless otherwise noted, the fabric is 100% wool coating and has been pre-washed. Quantities of a particular fabric are limited, so once it's gone it's probably gone. For thicker fabrics, it's suggested to make one size larger than you otherwise might.
