The marble effect is very easy to apply. First of all, buy some little jars of hobbypaint. Paint a green layer and let it dry.

After that take a light brush with soft hairs and dip the yellow with your brush over the whole jerkbait. Let it dry again and finish the bait in the tradittional manner.

Of course there are more colorcombinations possible. For instance White/Black and White/Red. Just let your fantasie go wild.

Just give it a try.
