i like this maybe someone else could use it ...

step 1 make new doc.(size doesnt matter), white bg

step 2 Hit D (for default colors), now click on the black make sure it is the foreground color , click it enter this #125D03.

step 3 now reset your brushes find the grass brush (the three bladed grass one) now brush the entire doc with this brush not entirely just like this...

step 4 go filter-sketch-plaster settings should be 29 image balance, 1 smoothness, bottom for light ... now you should have something like this

step 5 go filter-sketch-water paper settings should be fiber length 50, (set the brightness and ontrast to your likeing) for this i will use brightness 40, contrast 85


and there is your BG for different color of course Image-Adjustments- Hue/Saturation- check colorize and play with colors...

also i added mosiac tile and it gives it somehat of a matix feel too it...
(mosiac settings 100,15,100)
