Cling wrap backgrounds

I suspect everyone who has made their own backgrounds has already made these cling wrap backgrounds, but I never had. Learning from my mistake the other day when I tried to use Staz-on and alcohol for this technique, I changed my tactic this time. What I got were some of the most beautiful backgrounds, although they did curl a bit when dry.
Supplies from lower left clockwise:
Substrate (I used 12 X 12 heavy white cardstock)
Craft sheet and/or plastic to protect your work surface
Plastic cups (shown with paint in one, water in the other)
Cling wrap
Cheap acrylic paint
Mica powders (optional)
Foam brush
Not shown: rubber gloves and paper towels
Create a wash by mixing 1/2 water and 1/2 acrylic paint. Don't use expensive paints, since you are watering them down, anyway. This is one time when cheap is better. At this point, you can add mica powders. I used a metallic paint on this sheet, so didn't need the mica powder. Work quickly and make sure there is lots of wash on the page.

Cut a piece of cling wrap about 1 1/2 times the length of your substrate. Since mine was square, I ended up using two lengths to cover each sheet. Crumple the cling wrap.
Lay the cling wrap on the wet paper.

If you haven't crumpled it enough, you can still push and twist the cling wrap at this point. Set aside to dry.

You can also press the cling wrap with your hands to assure good coverage.

Set aside to dry. Yes, I mentioned that before, but you must leave the cling wrap on the paper until the paint is completely dry. If you don't the top layer of your paper will peel away with the cling wrap (don't ask how I know this).

One of my two favorite pieces happened as an accident. This background was made using pink paint and water only. I reused some of the cling wrap and thought I had used the clean side, only to find out that the copper paint from the previous background had transferred to the page. What a gorgeous accident I created. You should click on this photo to see the true beauty of it.

My other favorite background used green, blue, and copper colored acrylics. The colors sort of bled together in the process and created this stunning piece.

Here are all the pieces I created using this technique. I could have made more, but I ran out of room to dry them. It's a small craft room and I had no place to put them outside to dry.
