maybe make a carpenters star in the middle with a bunch of 6" squares around it. when you make it really large it will be easier to work with. the points on the star i would do in the lavender and the two lightest blues and then use the two darker purples and the blues around it. I would then use the last two pinky purples on the back. they are more of a hot color than a cool color. but that is just me. hope this helps.
