I love the purple, blue and black in your star. I think you shouldn't worry about what other's think of your color choices. If you are making items for yourself, pick colors you like. I too have a similar design wall, except I put in screw in cup hooks in the wood molding over the closet door, then tied a loop of string that hangs on the hook, another screw in cup hook goes in a piece of 1" X 2" that's in a sleeve in a big piece of flannel (wider than the closet opening). I have sleeves on two sides, so can have it two ways: long from top to bottom or long widthwise.
