Okay... this report was a bit dry in spots, but in a nutshell it discusses how an experiment was done using a variety of basting sprays, and fusible adhesives and how they hold up in quilts over the years. If you are looking to make long term (to live over 100 years) you might want to read this article and really decide the best routes to take when using any fusible sprays, webbing, batting or other adhesives. It deals with heat and light aging on your quilt
I found this while doing a bit of research for one you who PMed me earlier....
Cheers
