Here is another idea for you. I am hand quilting a large X in each completed block. so when it is all together the quilting lines goes at an angle each way. Then on my border I am doing straight quilting lines 2 1/2 inches apart. This was sujected to me by a woman who does machine quilting. She said the quilting would look rich, and not take away from the different sizes of blocks. If that makes sense. I will take a picture of the section I have finished and will attach in a bit. It still has the basting stitches in it!
