Knitting patterns for slouchy hats are available at RedHeart.com, CascadeYarns.com and Michaels.com. Some patterns are rated as easy for beginners, whereas others are designed for more advanced knitters.
The RedHeart.com pattern utilizes two different colors of yarn at the same time, resulting in a variegated design appropriate for any worsted weight yarn. CascadeYarns.com offers several slouchy hat knitting patterns, including a lacy, lightweight hat appropriate for summer use. One pattern also adds decorative buttons to the brim. The pattern at Michaels.com, designed for intermediate knitters, adds a knitted flower to the brim. The flower is worked separately, and knitters can add this embellishment to other accessories, such as purses.
