The ones I quilted for didn't want anything that would cause anyone to be uneasy with their quilt. So depending where you send them it would matter. Lots of things in different areas could cause problems, so where you send them is what would give you the guidelines. Just think if someone sent a, just for instance, cross fabric to the mid east. That type of thing. So I know that most of the groups have guidelines for what they can and cannot send out.
