Here you see the trees that because of the curtain you can't see through the window!
At first I thought that even with the purple tree (unfortunately, I couldn't get the color correct in this photo; it really is a purple tree not blue), I would make the trees realistic. The colors I chose initially were all green, but when I previewed them they looked dull and insignificant on the green background. That made me think it could be a fall scene with orange and yellow. Those fabrics came out next. Then I started to have fun - stripes and tiny patterns began to appear followed by a honeycomb (now that was a deliberate visual joke, a tongue-in-cheek reference to the pastel paper I used and didn't like). This still could be a fall scene, but there are quiet smiles to be had, too, I hope.
It's not a work of art meant to be taken seriously - it's just supposed to be as much to look at as it was to make.
