Scarf backing
 

Making a quilted scarf from scraps. Suggestions on a soft backing. Fleece, minkee, flannel?

All of the above!
Depends how bulky you want it to be.

A couple of other options ....
* one of the fabrics from your pieced side
* something light-weight and silky

Fireside would be nice if you happen to have some leftovers....
