Lee in Richmond

I had bought some 3" precut squares on eBay, and then tried to find something to do with them. I found myself rearranging what probably should have been random and creating some patterns. I put it aside, then needed a baby quilt for a graphic artist, who might think this is actually good...

I am not a confident quilter and usually resort to stitch in the ditch. Not all these lines run the same way, however, and now that it's sandwiched I see some of my intersections aren't perfect. What ideas do you have for how I can best quilt this? I have gotten so much help from you quilters that I feel I can ask once again.
