I didn't really expect the white on white idea to work. But I'm pretty happy with it. The warp is still 8/2 bamboo, and the weft is a thicker, softer knitting bamboo yarn.
And now for a little color, here is how my experiment with the Weavette turned out. The blue on orange almost made me go blind. I wanted to see if I used two very bold colors in a 7 shaft satin if I would end up with a solid blue side and a solid orange side. Pretty close, but those orange picks are pretty pronounced on the blue side.
