I started playing with diamond blocks – which are very easy to cut using a triangle tool on the fold. After playing with several ideas, I put the black and white framed ones vertically and the colored ones horizontally.

The idea is there, but I think I need to focus on sewing the diamonds into light, medium and dark colors for the 3 sides. That way it will look like 3-D boxes.
What are you playing around with lately?
