Except for baby/toddler quilts, every quilt I've ever made for myself or someone else and saw/used...Never even saw the back. Beyond that, If it really only goes with the other fabric from that collection, well theres that option. All the above suggestions are great, But the really main things is....Don't let it stress you out, lol. There are soooo many other things that slip into our lives we have to deal with, colors, quilting, sewing, creating is our joy and outlet.
