I've been experimenting with acrylic. I have been using stamps of one or two colors for my backgrounds, as in the two pieces below, but as you can see , the backgrounds get noisy sometimes. I like them for their colorfulness and the backgrounds are interesting if you take a close look, because of course I think most stamps are interesting, but sometimes the stamp backgrounds drown out my message.
Which is why I've been experimenting with painted backgrounds. They definitely make my pictures pop out more, though to me these backgrounds are a little less interesting. But the paint is really difficult to adhere the stamps to. They slip and slide all around, frequently become crooked and have to be completely reworked- it takes a lot more time to build on the paint background than on a background made of stamps.
Today I tried sealing the paint first, with varnish, before laying my picture down on the black paint, but the varnish and the adhesive had some weird chemical reaction and all of my yellow stamps looked gray from smudges of paint! Very disappointing- especially because yellow stamps are incredibly hard to find- countries just don't make many yellow stamps for some reason. Luckily, I was able to take the whole picture off, repaint the canvas and rebuild another yellow house. I actually like this one a little better than the first one, so I suppose it all worked out.
Here's my latest miniature canvas 'Spring House':
