I just learned how to brioche, and love the texture of the fabric! Especially the honeycomb stitch, I just had to cast on a cowl directly... It makes a very warm, two-layered piece.
The finished measurements of the cowl are:
Length: 110 cm (44 inches)
Width: 19 cm (7,6 inches)
The gauge of the yarn is 22 sts are 4 inches in stockinette stitch, in pattern it is 15 sts are 4 inches.
You will need approx. 150 g of DK weight yarn.
