One way to get it to lie flat is some thing that I learned recently and that is when you sew it together, don't sew through the center seam and it will lie flat. Mine last one did and it was a perfect match, but the dern quilt went wonky in the squaring up on it. I can probably save it, but I put it away for the time being. I've also done the ones from quiltsmart.com and they are really easty to do. Love them. Have agreat day, Huggies, FAy
