I am on a roll with the triangles - or should that read on a straight edge lol.
I have sets of CU overlays for you and also played making some papers with them.
Simply Patterns 4 is my first set of triangular based overlays for CU.

Simply Patterns 5 is a set of ten patterned overlays in jpg format.
You can simply place them over a colored background and play with your blending modes for varied effects or layer them with paper and textures to get more involved effects. They can even be used over photographs for some interesting effects.
Each overlay is 12inches at 300dpi.
These are ok for commercial use.

Patterned Papers 6 is a pack of 12 inch digital papers.[300dpi].
This set is based around the triangle design element.
All 10 papers in this set are individually patterned and textured.
Use these for your scrapbook backgrounds or in your digital art, journalling or crafts.
These ones are for personal use.

Thanks for reading and enjoy your scrapbooking.
