heavy cotton / acrylic flannel fabric for blankets, work clothes, winter weight shirts

Burgundy wine colored brushed cotton / acrylic flannel fabric, heavyweight for winter or work clothes (chore jacket lining, or flannel shirts, or maybe a quilt backing). This is 70s vintage, I think?

The fabric is 60" wide x 2 1/2 yards - a little dusty, but unfaded, never laundered. Nice and soft, looks really warm!
