I'm planning on painting a gold stripe(band) and also some intricate details. I'm not sure how I can paint it without streaking. I'll be using airbrush colors...any tips?

I don't have an airbrush system so have only used regular cake decorating colours.
If you mix them thick enough, like real paint, you don't get a streaky look.
Good Luck!!!

Cakes47, thanks a lot for the tip but do you think it will give a stripe a nice even look?

I don't see why not. But you do need a good steady hand. You could put a
band of fondant around the cake and then paint on that to make it easier.

You could mask it off with painters tape too.

Get yourself a tiny white foam roller and roll it on--you should get a perfect coverage and you can lightly go back over it and remove any bubbles that may show up.

Thanks everyone for the tips! Will definitely try all of them. THANKS AGAIN!
