[QUOTE=HillCountryGal;5695055]Guess my answer to all your questions would be.. think of how all this will behave once it's washed. If it won't lay right, then I'd at least tie them if you don't want to quilt.

One time I made placemats. Since they were so small, I didn't quilt them. That was a mistake. After they were washed, they were a mess. So I ironed them good and quilted them. Afterthat, they washed up just fine.
I don't quilt a lot on wall hangings, but those are not to be washed.
