For the base I've used lovely thick papers from Authentique's Faith collection. The pointy crown bit is die cut using A Gilded Life - Petite Monarch Crown Long Die. The flowers and leaves on the crowns are from Petaloo. You could use anything from their Botanica line and it would look divine :)
The crowns are finished off with some inexpensive clear acrylic snowflakes and a good dose of glittery snow.
I can't wait to take these to the Plum Pudding Market next Saturday! The market is a small Christmas sale I'm organizing, featuring 20 outstanding makers and artisans. If you're near, you should absolutely check it out. It's going to be a lot of fun :)
