so I made some color flow flames for a harley davidson cake i'm doing. got some great ideas on here. so when I removed the symbol it broke 
the flames came off good but i'm afraid to attach them to the cake.
1 was because i was told it would melt against the fondant where fondant has grease in it.
and two is because i don't know how to attach them. do i use royal icing??
someone help pleasseee
Yes attach with royal icing. I haven't had any of mine melt or anything, but I guess it could happen.
I wouldn't think that RI would be a problem for attaching. However, I have done a little "test" to watch what happens to a color flow piece over time. I made some of those wee birds from the Wilton course 2 book. I inserted them into a buttercream iced cake (as they are in the course booklet) versus just laying them on top of the cake (which I have also done). After 24 hours, they were still standing but getting a bit soft. After a couple of days, the birds were wobbly and way soft. When I tried to pick one up and take it out of the BC, it crumbled and fell apart. It couldn't be picked up. I don't put a color flow piece on the cake until within hours of needing it.
