I had lots of fun making all of these backgrounds. I started with oil pastels then Stencil Girl Stencils and used Distress Inks or Pan Pastels. The metallic gold Pan Pastels are yummy but don't photo well.
The photo on the top left is scribbling with oil pastels on a manilla file folder. The next photo is using a cotton ball with baby oil to blend. The final is using a stencil and Distress Inks. You could also use chalk. If you stamp, be sure to use a permanent ink like Memories or StaZon. NOTE: embellishments need to be adhered with something similar to Crystal Laquer as the oil won't allow a good bond. This is a fun and quick technique!
