I was thinking you might find a multi-coloured batik that would work for the flange strips.
I just went back for another look ... and noticed that there are Impressionist Blenders to go with it. I'd sure be looking at using them!
Then I was curious if there was something via Google.
Better still ... I found you a virtual design wall. Unfortunately, I don't think you can cut up the fabric, but you can play around a little ............
