I know the thought "what if she doesn't like it?"
I think your idea would cut down on people expecting quilts for free.
If someone asks for a quilt, then I think asking them to foot some of the cost would determine how serious they are.
I enjoy the piecing more than the quilting. And flimsy's are easier to store. So I have no problem leaving them behind.
I'm dense when it comes to "would this be rude".
