My daughter was happy with hers just like this.
But mine needed more. So I used a snowflake stencil to add some blue Lumiere paint -- you can see where I glopped it on in the center -- this was not intentional, I misjudged the amount of paint I had on the foam brush.
After the snowflake globs dried, I thought it still needed something, so I brushed a light coat of diluted golden yellow Setacolor transparent paint over the whole thing. Then we made 3D stars from the paper-cloth.
