Both these methods are so simple, and fast too! Well, the second technique has some drying time, but it IS quick to make.
Deli wrap adds translucence to this first idea. I photographed it with some lacy black paper underneath (in the upper left corner) to show how sheer it is.
I simply used water and alcohol inks to create a random, distressed-looking design.
The second method requires sturdy paper or card. Use a painting knife to apply either texture paint (as shown here), molding paste, or heavy gel medium.
While it's still wet, embed tiny beads. These red ones are very small no-hole glass beads. I also used antique gold glitter, which looks white in the photo below.
When dry, seal with clear fluid acrylic medium.
