For the background I used Zig clean color real brush markers. I first scribbled 5 different blue/green colors all over my watercolor paper. Then I used a wet brush to spread out the paints and blend the colors, as well as drawing the outlines of the background. The colors from these Zig markers are so vibrant. I didn't need to create multiple layers like I normally do with normal watercolor.
After the background was created, I used silver embossing powder to emboss the constellations. I also splashed some water and appiled the same silver embossing powder to create random star effects. At this point, the background is finished and the rest is simple!
