I took my Mystery to several groups of friends and got two conflicting points of view. One group thought the green metallic would look the best using blue pearle cotton(798) and the blue Impressions(7041). The other group thought the blue metallic was better, using the purple pearle cotton (327) and purple Impressions(6010). So my guess is that I will be able to do some mixing and matching as I stitch this piece. I think my preference is for the blue metallic. I think in person, the green is too green. I am not sure if I will use the blue or the purple as the dominate color, but right now it looks like green will be an accent color.
