I'm making a rose cake and want to tip the flowers with color.

How do you do this?
Should I line one bag with white then put a bag in center for the top color?
I need to sit and play

thx!

Do you mean like this? http://zoebakes.com/2011/04/22/how-to-pipe-icing-roses/

YES! But want to put the roses all around cake :) hmmmmm

thank you!

Here's one method 

but I usually take some color paste on a skewer and and paint a straight line starting from nozzle going up at 3 places equal distance in the bag, then fill with the buttercream. Your flowers will have an edge of the colour you painted.HTH.

PERFECT!!!!!!! THANKS
