Needle Knit Seagrass Slouchy Hat

Needle Knit Seagrass Slouchy Hat

By Kristen Mangus

Meet the textured sister of the Sisal Stitch: the Seagrass Stitch!  (See full details and videos of both stitch patterns in this post.) This stitch has a natural slant to it depending if your are whether you work it to the right or left.  The Seagrass Slouchy Beanie quickly knits up in the round as a woven spiral and looks fantastic in the reverse as well!

This quick knit pattern works up in no time in a stitch that resembles natural seagrasses in the ocean. This pattern is perfect for beginner knitters because the seagrass stitch is easily worked in the round.  You will need to know how to connect in the round as well as purl for the brim. The Seagrass stitch pattern is demonstrated in a video tutorial.

Grab the companion pattern for the Sisal Cowl or the Sisal Scarf for a unified look. Both stitch patterns have a distinctly woven look that you’re sure to love.

Beanie is worked in the round.

I recommend the Longtail cast on, but you may use another cast on method if you prefer.

To change yarn or needle sizes cast on a multiple of 4 for best results on stitch pattern and brim ribbing. Main stitch pattern is a multiple of 2.
