A friend asked me about a hat that would accommodate her sunglasses or eyeglasses without creating a gap which allows her temples to become cold. I made two hats and wrote out the patterns which I am sharing here with you. This hat has a double-layer cuff, the other hat has eyelet openings.

Description:
This hat features a double layer cuff, with openings between the 2 layers to accommodate wearing eyeglasses or sunglasses. This feature to accommodate glasses may also be adapted into a sewn fabric hat, or a sewn lining for a knit hat.

Knit in the round, this hat may be worked in any stitch combination desired, such as ribbing or cables from your favorite stitch dictionary. The design shown here is a 5 x 5 rib with alternating knit and purl checkerboard squares.

In this hand knitting pattern, the inner cuff layer is knit first, bottom-up, then is set aside while casting on and knitting the hat’s outer cuff. The two cuff layers are knit together leaving openings appropriately spaced to accommodate eyeglasses or sunglasses. The main body of the hat is worked in any stitch combinations desired, and the crown or top of the hat is completed with decreases.

Skill Level:
This hat may be confidently knit by an intermediate knitter. Time estimate: 10 hours.
A highly motivated beginner may also complete this hat successfully, by patiently dedicating more time.
