Use of Textures - for all Photoshop users, insert your texture ontop of your piece of art or layout. Then, in the bottom right corner is the layers tab. You will see the word 'Normal', just below the tab 'Layers' and next to it, a tiny arrow. Click on that, and you will see that a list of settings drops down. These change the colours, darkness, view etc. of the texture. 'Darken', 'Multiply' and 'Overlay' will work nicely with the textures below, but fiddle around to see what matches the style. To fade the texture, next to the drop down box is 'Opacity'. Use that to make it lighter.
