Colored Paper Cut Outs Set Two

Here is another set of my paired designs. I really do like them. I think the biggest weakness is that there isn't a lot of visual variations between the designs. They are all, except for third row middle, a centered motif, similar to a quilt square. As I develop designs, I really want to find ways to integrate the entire space. On the stitched sample that I worked on this weekend, I began to work with the background more to make it more of a part of the design, not just a pretty pattern slapped onto any old background. Suggestions???
