I love the texture of the Irish Moss stitch. It is very close to the moss/seed stitch but you double up the rows to get more of a diamond shape that comes together with to form a cool diagonal line pattern which looks so amazing knit up in a bulky wool. Mix that with a long brim that is long enough to fold for extra warmth on cold days and a slouch in the back to make a cozy warm and stylish textured beanie.

This hat is knit up in Cascade 128 Superwash Merino Wool. It is bulky weight and so squishy soft, especially after the first wash, which makes this beanie so cuddly and warm. And because it is superwash you can just throw it in the dryer after a snowy day playing outside. The colour I used for this one is dusty blue which is absolutely gorgeous. It is a very muted greyish blue which shows off all of the textures so beautifully.

Cut the yarn and run it through the remaining stitches and into the center of the hat with a darning needle. Sew a couple stitches on the inside to keep from getting a hole in the center.

Weave in loose ends

Handwash and Block
note: superwash takes a little longer to dry than regular wool and it may seem a little stretched out when wet, let it air dry after the first wash though, it’ll be worth a wait.

Wear and Enjoy
