For the GPP Street Team Crusade No. 55, it is about blending two colors in a background and then stamping a large image with those two blended colors. The interesting part is that this is supposed to make the images drop-out of certain places.
I don't have a lot of stamps. As a matter of fact, I don't have any large stamps. So I decided to work with the closest thing I had - stencils. Already excited about fall colors, I went with a wet-on-wet watercolor background of purple and orange. While it was still wet, I placed a stencil over it and sponged on more purple and orange watercolor. It blended really well and because it was still wet, the stencil actually pulled some of the watercolor away, leaving light outlines around the stenciled parts. I like how subtle the images were, but I wasn't sure that I was going in the right direction.
I started to pull out what stamps I did have and found a stamp that looked like it was sort of big enough to work. Again I worked wet-on-wet painting in a big rose-colored heart and random shapes, then pushing in some purple around those shapes. While the background was still wet, I stamped "all my love" with some rose and purple watercolor. The words are still visible but slightly blended in with the background.
Although I liked how the stamp blended with the background, I thought I would try painting in the background wet-on-dry and then waiting until the background was dry before I stamped over it with more watercolor. I think it would have looked better if I had done a wet-on-wet background, letting it dry and then stamped - something to try later!
One last try for now - I decided to try this process out with ink. I mixed a 50-50 mix of water and ink of yellow and blue, then quickly brushed on some yellow ink. While the yellow ink was still wet, I quickly brushed on some blue ink. The ink seemed to dry pretty fast, so by the time I placed ink on the stamp the background was dry. I noticed that the yellow didn't seem to show up on the stamped image. Either I didn't put enough yellow or it mostly merged with the blue. Either way, it made the stamped image stand out more than I thought it would.
Now I'm off to figure out what I want to do with these backgrounds!
