The Lone Star pattern can be difficult to get perfect. You can either cut bigger background pieces or redesign it. How about taking the background off, separate the star into two halves and appliqué the two halves on either side of a whole piece of fabric. The center of the star would be on the straight edge of the whole cloth with the arms across from each other for a new design. The fabrics are very pretty together in the star. Someone posted a picture of their star quilt with the star set on one side of a whole background and it was beautiful.
