For a friend of a friend who wanted slate grey, white, and slate blue.

980.1g of yarn total. Based on the sizes of the partial left-over skeins, I’m going to say it was pretty close to 1/3 of each color.

In order to get the thickness I wanted, I chain-plied the yarn, effectively using three strands at once.

I did one row of the white, two of the other two colors, and carried the yarn up the side.
Because of that and because of the numerous other examples here on Ravelry, I did the two-rows of sc edging.
