The best fabric for quilt backing is either 108" wide backing (no seams, one cut covers a queen) or standard quilting cotton pieced to size. Backing should be the same fiber as the top — 100% cotton — and 4" larger than the quilt top on every side. Wide backing runs about $21.96 per yard but covers nearly three times the area of standard yardage.
The back of a quilt gets decided last and touched most — it's the side against you on the couch. The good news is the choice is simple: wide backing if you'd rather not sew seams across six feet of fabric, pieced yardage if you want the back to match the top's fabrics exactly, and flannel if the quilt's job is to be maximally cozy. Here's how to choose and how much to buy.
Connecting Threads
A quiet ivory texture print that disappears behind any quilt top — the little pattern hides quilting wobbles better than a solid ever will.

Your backing must be about 4" bigger than the top on all sides. In 108" wide backing that's simply the quilt length plus 8", so a 60x70" throw needs about 2¼ yards. In standard 42" fabric, plan on two lengths seamed together — roughly 4 yards for that same throw.
It's tempting and occasionally fine, but most sheets have a high thread count that's genuinely hard to hand quilt or free-motion through, and percale can pucker. If you try it, choose a low-thread-count 100% cotton sheet and expect your longarmer to sigh.
Match the value of your quilting thread, not the top. If you're quilting with cream thread, a dark backing will show every stitch — beautiful if your stitching is confident, unforgiving if it isn't. Busy mid-value prints hide the most.
Flannel backs make wonderfully heavy, cozy quilts — buy 10-15% extra for shrinkage. Minky is loved for baby quilts but it stretches; pin generously or ask your longarmer, and never prewash it.
Yes — the quilting process shifts the layers, and longarm frames need fabric to grip. Skimping on backing margin is the classic way to end up with a corner that doesn't quite reach.
