This eye-catching brioche blanket is inspired by Japanese sashiko embroidery done with white thread on indigo-dyed fabric. The bold, graphic stitch pattern is based on the traditional seigaiha wave motif.

The blanket is made with a super-bulky blue yarn and a worsted-weight white yarn, which creates an interesting variation of traditional two-color brioche without any added difficulty. The contrasting yarn weights give the navy blue background greater color dominance in the design, which is meant to reflect the pattern’s inspiration of white embroidery stitches against a background of indigo fabric.

This pattern should be very approachable for any knitter who is familiar with two-color brioche knitting, because only one type of increase and decrease is used throughout the blanket to create the motif.
