I don't think anyone can have enough overlays, especially ones as easy to use as these. All you need to do is plop one on the top layer and set the blend mode to multiply and maybe adjust the opacity a little bit. Best of all, they have little to no impact on the colors in that paper you've worked so hard on. But don't let the ease of using multiply keep you from experimenting with the other blend modes. This product contains 6 full size (12 x 12) highly detailed JPG files that have been saved at 300 dpi.
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.
