I would like to do the "Quilts of Valor" challenge (Nancy's Notions). Each of the quilts will be donated to the military. I had originally thought of doing Cathedral Windows, and put a flag or star in each window, but because of the time limit I don't have time for all of that hand work. My next (and only other)thought was some form of Log Cabin. The colors must be red, white and blue. Does anyone have any idea(s) of other blocks I could use? The finished quilt will have to be about a twin size. Any suggestions will be greatly appreciated!
