I have made a couple of quilts using this method, before I saw Jennies video.However, I started with the 4", then the 5" was on top of that, next was 7 or 71/2 can't remember, then a 9" block. When done this way the finished blocks
really go together beautifully and makes a lovely quit. If you use more additions than Jennie did, would not recommend starting wit a center or first block larger than 4". I first used a 6" block using my method and when it finished out the completed block was an 18" square. This is a quick and easy quilt to do.
