Clear Coat Finish Spray
The crowns are sized for a 24" mat. I wanted a smaller crown to sit on top of her head, so I sized down to 12 inches and cut out on a heavy cardstock.
Paint the Mod Podge over the entire surface of the crown, working fairly quickly. I used a mixture of silver and gold glitter and poured on top. Let that side dry completely, and do the back side as well.
