Hello there, I coloured a white paper with coffee (yes, with coffee ) and scanned it. Then I pasted it by using a layerstyle like "overlay" or "multiply". But I used more textures, on the bottom left there is a bark texture and the dark border on the top is created by an old book I scanned. Then I added a gradient and erased or masked all distracting textures on top of the drawing. It was a lot playing around with opacity and layerstyles.
