i'm assuming you have checked the Wilton Course books. I know the old course books that were phased out in June have it. I think it's the course 3 book. They may be hard to find. Since Amazon or e-bay
Check out the flower tutorials posted by Ryaln in the How do I section. JenniferMI sells some great cutters for them (sugardelites.com) They are not hard to make, I made about 40 of them last year for a cake. LOTS of parts to each one though!
