Made with cardboard, purple paint and glitter(lots). You have to make tiny holes for the lace before aplying the glitter and be careful to don't close your mini holes by accident. Use a old pencil or a chopstick to help you with the glitter painting, so you get a flat surface.
I suggest ( I didn't do it, but maybe is easier ) if you paint and add the lace before you glue and close the whole thing.
