There have been a couple of threads lately about these items.
I started to wonder about my batting choices and did a little research. I am pleasantly surprised, and I also learned something about basting spray. I posted to the current thread, but I think this is information everyone can use, so I'm posting this link here, too.
Here is the link to the entire study for anyone wanting complete information:
For anyone wanting the short story, here is the conclusion of the study:
'Fusible battings appear to be an acceptable commercial adhesive-containing product for quilts intended as heirlooms or for sale to collectors or museums.
All the quilt-basting sprays, except Spray and Fix, were associated with significant yellowing or strength losses following both shorter and longer periods of heat-aging and light exposure.
Fusible webs, while acceptable for quilts intended to last for a lifetime, could not be recommended for quilts intended to be handed down from generation to generation or for studio art quilts intended for sale to serious collectors or museums.'
