quilt size: I have another question to ask here. When I drew up "my plan" for a Grandmother fan quilt, I wanted all blocks to lay evenly along the top, with a sashing edging the bed. Sewed my top together, and it worked exactly the way I wanted it to fit. Since I wasn't into hand quilting yet, my quilting was minimal, outlining blocks and fan blades. I used a low loft batting. After the quilting was done, my quilt will only fit properly on a standard full size bed. Is there any way to determine how large to make a quilt so that it will fit properly after quilting?
