I am making a baby quilt that is about 50 inches wide. The fabric I chose for the backing is 44. I know I need to use 2 lengths and put them together, but my question is: Are there any guidelines about how to put them together? I don't really want a seam down the middle, but should I make the middle section larger than the sides, or do even thirds? I can do the body of the quilt in one piece and add a strip on each side the same width as the outside border. I have attached the picture of the top if this helps. This is the first time I have made a baby quilt wider than the backing. Thanks for any help.
