I think you will have a very pretty quilt using just what you have. I have 64 blocks done for a scrappy log cabin and I used different lights in every position but I almost wish I had not used so many different lights. On the light side I think mine would have looked better if I had just stuck with 3 or 4 lights. Oh well, lesson learned. Are you using more fabrics on the dark side or will all the blocks be like the one you show here? I like the one you have here alot! Will be anxious to see your quilt finished.
