I have no idea age of fabrics. I have been very surprised at quilt museums where experts have dated fabrics and I would swear they were a more modern era. If you like the piece and think you have a creative idea go for it! I've seen some awesome results of friends who found old, worn, stained textiles and quilts and when it was "repurposed" they had a treasure. It's yours and you couldn't buy the fabric for $2 :-)!
