Great advice, Picky. Practice on something easy, then the other things will come. As far as transparent material, I've found it's not really a case of lowering the opacity of the layer to get the right look. When you lower the opacity, you also lower the power of the color and saturation. Try this: Try painting on the cloth using the color of what you want to show through. If, it's the sky in the background, use some sky color to paint in the areas you want the cloth to look more transparent. Be careful to pay attention to the folds where the cloth is doubled up and is more likely to be opaque. Good luck :) Will
