The capstone flower in Wilton's Course 4: Advanced Gum Paste Flowers is the stargazer lily. It's a very versatile flower; with just a few adaptations, you can make a tiger lily. You'll need orange gum paste, thin pink and purple shaping foam, gum glue adhesive (a pinch of gum paste dissolved in a tablespoon of water), a 9" fondant roller, a dusting pouch filled with a 50/50 mix of powdered sugar and cornstarch, a brown food-safe pen (I like AmeriColor's Gourmet Writers), the ball tool and veining tool from Wilton's 10-piece Fondant and Gum Paste Tool Set, the large and small lily cutters from the Course 4 Student Kit, orange and red Color Dust, small brushes, green florist's tape, six 6" pieces of 22-gauge florist's wire, the petal veining mat from Wilton's Flower Impression Mat set (you can see for yourself why this impression mat is superior to the one that comes with the Course 4 Student Kit here). You'll also need a wave flower former.
Here's the set-up for coloring and finishing the petals (red and orange Color Dusts), brushes, the brown food-safe marker, and florist's tape.
stargazer lily; the assembly is exactly the same. I think this is officially my new favorite gum paste flower!
