Perhaps you could share a bit more information? New, old, fragile, sturdy, valuable, not valuable?
I've just finished treating and giving display advice for a monumental and culturally important quilt - 29' x 33' yikes - but big or small, overall support for long term display is important. Fabric covered tilt boards can be very useful.
At the very least, wide Velcro at top edge for new and/or very sturdy quilts is the generally accepted standard for hanging in textile circles.
Machine stitch fuzzy side to washed twill tape or washed fabric and then hand stitch the fabric edging to the quilt top. It's best if you can hide new stitching within quilting pattern.
Hook side of Velcro can be stapled to sealed (generally 2 coats of water based urethane allowed to cure for 6 weeks though better methods are also available if necessary) low emission wood like bass or poplar and screwed to wall or frames backing board.
Re the framing end, I defer to the large scale specialists!
