A couple of years ago I was able to attend Ricky Tims's talk in Oldham, and was able to handle one of his quilts that had the Ricky Tims Stable Stuff in it. I believe the quilt had been washed, and I have to say that I was a) amazed at how thin it felt, and b) would not have believed that it had the extra layer of Stable Stuff in it, if I had not been told. I would suggest talking to the Long-armer to find out her side of the story, it will probably be fine to leave it in with no problems what-so-ever.
