Thank you everyone for the comments, suggestions, and also the kind welcome. As suggested, I washed and dried a 1-yard cut (hot water, hot dryer) to check shrinking and wrinkling. It shrunk about 1/2 inch over the 36", which I thought was OK, and the wrinkling was not bad at all. The only concern I have now is that the fabric, now that it has been washed, seems a bit lighter weight than my typical quilting fabrics. So, I think I won't use it for piecing, but for backing. Thanks again for all the suggestions!
