For those sunny-then-gray days, a warm layer that’s small enough to stash in a pocket is always welcome. Our Foggy Day Hat pattern is just the thing, lightweight, effortless, and made with just one skein of our stunning hand-dyed Estuary yarn!

Nearly every stitch of the Foggy Day Hat is a knit stitch, leaving your attention free to admire the shifting colors of this beautiful yarn. You’ll knit the generous cuff in the round starting with a relaxed rolled edge, then turn your work inside out and continue the body in stockinette (still all knit stitches!), shaping the crown with spiraling decreases. Fold the cuff up to show its stockinette side, and don your finished hat. So full of easygoing elegance, it’s sure to earn a place in your pocket!

A luminous, fingering-weight single ply of merino wool, mulberry silk, and linen, Estuary knits up into a soft, fine fabric rich with movement and life. Its eye-catching silken luster is balanced by a touch of wildness from the linen that sprouts from the yarn, all anchored by merino’s gentle resilience. Hand-dyed colors roll like fog banks across the warm white ground, drifting gently in and out of view.

Pick up a skein of Estuary in your favorite hand-dyed color, including 4 brand-new ones. We picked newcomer Spider Web and longtime favorite Violet Hellebore for our Foggy Day Hats… What color will you be wearing on the next misty morning?
