Shirley, Shirley, Shirley..........the "R" word is a no-no. If you use it it means there are police to enforce it and they didn't hire Patrice because she wouldn't arrest anyone.
What I do is:
read the manufacturer of the batting to see what their recommendations are.
Then I take a small piece of batting to pull, push, wet, and try it to see what happens with use (the more it mats, comes apart, etc, the more quilting stitches I use)
If you use a natual fiber it holds together better than the fiber fill type that mats up and doesn't hold shape.
If all that fails..........well, who will know? Patrice will never visit, she's to busy.
