I have a wedding coming up this summer. The bride wants white buttercream icing with LOTS of black scroll work. My quesiton is, what is the best thing to use for the scroll work?

I had a cake disaster a while back where I used all buttercream and the black bled into the white. Would doing the scrolls in royal icing prevent this from happening?

Thanks for any advice you can give!!

are you covering the cake in fondant???? if so I would definitely use royal, or melted chocolate. If you're using buttercream....maybe chocolate wouldn't bleed like black buttercream...
