vintage unbleached cotton fabric, rustic homespun type material w/ coarse weave

1970s vintage 'homespun' fabric, a natural pale tan color with brown and yellow gold flecks.

I think this is probably all cotton, but it could be a cotton / poly blend? It's heavy and soft, not stiff or firm.

This is a 45" wide fabric, almost 4 yards. Condition is very good, never laundered, nice and clean.
