Let me preface this by saying that I do not have access to an airbrush system.
I'm making a round birthday cake for my son, and I want the bottom border to be a snake. I would love to paint on a snake skin pattern somehow.
I've searched the net and have found tutorials for spray painting using netting for various non-edible projects.
I'm wondering if anyone has any suggestions on how I could do this using food coloring and paint brushes?
What about going to a large craft store - visiting their cake section and purchasing cans of spray color available today.
If you are putting it on a fondant covered cake I would try to hand paint it on using gel colors mixed with a little vodka. I love the effect of painting on fondant. It is a perfect canvas. Just make sure not to thin the colors out too much or it will run.
take the netting ( the kind that oranges and onions comes it is good) and stretch it over the fondant so that it slightly embosses it. Use colour dust (wilton - easy to get, petal dust - cake supply stores,online) and lightly brush the colours you want over the netting. that should give you a pretty good snake skin look
