Thanks to everyone for the ideas and tips. Fortunately what I have is not 70's poly - that was pretty yukky stuff for sure. I also found some beautiful red washable wool - 6 1/2 yds. Have NO idea what I was going to make but used with other washable wools could make some a lovely quilt and back with the red. My mind is spinning now - need to write these ideas down before I forget AGAIN how I was going to use it.
