I did this design several years ago when I was taking color theory, as a papercut. It was my favorite of several I did at the time. Red-violet & blue-green, two colors that are both capable of looking either warm or cool, depending on context. The idea is that it looks like a light is shining through the page.
The inspirations for this series of designs included Harriet Hargrave's books on Baltimore Album papercut-design quilts, and the symmetry of William Morris' fabric designs.
I always thought it would be fun on a t-shirt. Now, with Cafepress, I just have to send them the design to have it on a tee. Also, of course, a pillow, and a tile box and a round ornament or magnet. This version has been Photoshopped for richer color and some texture.
With luck I'll have a new section for it up at Cafepress this weekend. Leave me a comment if there's any particular item you'd like to see it on that I don't have.

I got the whole section done up at Cafepress, including the new color t-shirts, and my new color variants on the design a few weeks ago. WRW Color by Design
And now, at Spoonflower, I can have one of my alternate color versions tiled as fabric, unique custom fabric, digitally printed!
