I had to think about and look at my fabrics and google images to decide which was which. Then I decided that a little turquoise really went well with black, gray, and aqua. I strayed from my formula of making a frame of the target color but I think this still will look okay with the other blocks. I am out of town, but will post a picture when we get back of all the blocks together. In the beginning I was afraid there would be too many mellows, but now the brights seem to be taking over!!
