I really love both these fabrics, but they are so similar in color and value that any 2-color pattern will really not show up very well. I think all the pieces will just blend together. Can you add a third fabric, maybe that very, very pale blue (or am I seeing a really, really pale purple in there?) and maybe a little bit of navy to match the thin lines in the one on the left? With the additional colors a larger array of patterns would be possible.
