I recently bought a vintage quilt top. The stars are all sack cloth or dress cloth, but I can't figure out what they are appliqued onto. It looks like unbleached muslin, but it is heavier and has a little stiffness to it. Also, any ideas on what I could used to back this with? I'm sort of new to all this. my grandmother quilts and sews. I have dabbled in and around fabric and sewing all my life, but am getting more and more interested as I get older.
Thanks for any help y'all can offer.
