Figure out how large your quilt will be - including how many rows & blocks to equal the width and length. Take your diamonds and enlarge them so that they will not have to be so many. Adding extra rows may be nice too since you are only using two - my rule of thumb is never an even number. You can also add borders around the finished product to enable you to do less little diamonds. Try either way...you just may love it! There are diamond rulers in any fabric store that should be able to help you a bunch! Good luck!
