This is what you see when you look on the back side of one of my handpainted backgrounds ... lots of messy stuff. Actually, I've made it better for you by making it grayscale AND transparent. This pack contains 4 full size (12 x 12 in, 300 dpi) transparent overlays saved as pngs. You can color them, clip to them, or just use them to grunge up your papers.
These overlays are ok for commercial use along with S4H, S4O, and Personal Use friendly. You may also use them for creating freebies.
No credit required for the use of these items, but it's definitely appreciated.
