I love green...favorite color...all greens, especially the darker ones and the avocado greens. I don't use the really bright greens, tend to stay with the duller ones because of the colors I like. There are a lot of shades of green, and different ones go better with different colors. I have 2 bins of red, 1 bin of blue, 1/2 bin each of purple and pink, 1/2 bin each of yellow and orange, and 4 bins of greens (as well as bins of black, brown, tans, and lights). I think the more you work with color, the better you can figure out what is the best green to use with the other colors you are choosing for your quilt.
