You could probably do a rail fence that would look good. I just finished a quilt in blue/orange/ and white. The blue is darker than sky blue, but perhaps it could give you an idea of what such a quilt might look like. This is a chevron quilt, which is made of half square triangles. It was a challenge for me to make, and a rail fence would have turned out looking about the same.
Okay, let me find a picture, in case it "rings your chimes."
