I recently purhased a quilting pattern book called Link to the 1930's Making the Quilts We didn't inherit. I want to make this quilt as pictured with various patterns of feed sack materials, but not sure I want the backround to be white. Just thinking about yellowing and getting dirty maybe quicker then say another colour. So not being sure as to what other colour to use besides white I'd like to get some suggestions from you all. Looking forward to hearing your replies.
