Thank you for your kind comments. The brooch mould is a Ruth Rickey mould.... you can purchase it online from her site. The brooch is made out of gum-paste, then dried, and then I painted it with a super pearl colour dust for the pearls and in a gold paint on the rest of the brooch. To add extra sparkle, you can dust it with a small amount of disco dust. Hope that helps.
