New to this and I am trying to make a sugar rainbow to go onto of a cake. If anyone has any ideas on now to do that it would be a huge help! Thanks! Kelly

What do you mean by a sugar rainbow? You can color fondant/gumpaste in rainbow colors and make one that way.

If you're looking for something kind of see-thru, like stained glass, you can pipe royal icing in the shape you're looking for, then fill the spaces with sugar. Use like a #4 tip, though. Sugar will go right over a 0 tip piping.

what about using airheads sour belt candies?? My Dollar General store sells them individually for $.10/each
