I modified the Chinese Wave on the diagonal to make my 3 corner washcloth for face and body. This is thicker than my 3 Corner Cosmetic Cloths, and big enough to wrap around my shea butter body bar.
I knit up more in two different colors; one color for the neck down, one for the neck up. Just toss them in their own lingerie bags for washing and drying.
To make my 3 corner washcloth for face and body: Using 2 strands of Pigsah's Peaches and Cream cotton yarn I followed the modified Chinese Waves pattern to about 35 stitches on the needle and bound off to create my triangle.
This knits up fast, soft and cushion-like wth the 2 strands. 100% cotton, 100% reuseable. I thank Margaret K. K. Radcliffe for the Chinese Waves pattern and ailurokat (Ravelry) for the modifications to knit the pattern on the diagonal.
