I read about this design over and over again and thought "what's the deal"? I have now discovered what the deal is....it's the uniqueness of the pattern! The piece is knit on the bias so the variegated yarn makes diagonal stripes while stitches are dropped to make a pattern in the opposite direction.
My Clapotis is now half finished and knit using 1 1/2 skeins of Blue Heron Rayon Metallic-Sport Weight, colorway Cayman, on #7 needles. Since my yarn selection is a rayon fiber I wanted a slightly tighter gauge and went down to the #7s instead of #8s. One additional set of 12 rows were added in section 2 (increase rows) and there will be 12 additional rows knit in section 3 (straight rows). This scarf will be nice and drapery!
The piece will be finished by adding an edging of 2 rows of single crochet.
What's not to looove with those Metallic flakes?!
