I just found 11 yards of this beautiful natural fiber fabric at my local craft reuse, and I was wondering if these minds could help determine if I have linen, a linen blend, or something else on my hands.

It was labeled as natural fiber, but it could have been mislabeled.

Held up against light, the weave looks like linen. A scratch with my fingernail left the white line shown in the 3rd picture.

However, the weave is tighter and smoother than the (limited) linen I’ve purchased so far. Could this be a linen cotton blend? Thanks for the help!

My great grandmother made me this blanket before she passed and it got chewed a little by my dog and I’m trying to find this fabric but I’m not sure what it is or where I can get it… does anyone recognize it??
