Hi Dawn, I think a lot of the answer has to do with the final use of the piece. I used to be a strong believer in not cutting away behind applique ... until I took Suzanne Marshall's class at Asilomar. Her rationale for cutting away has to do with creating fewer layers to quilt through if you are hand quilting. She also is careful to align the grain lines in the background fabric and the applique pieces because that way, they stretch in the same directions. She does say if you're machine quilting, then it doesn't matter so much about cutting away, unless you want the applique piece to puff up more, in which case, you cut away so that the batting will fill that space. Since you're going to be sending this particular piece on, it probably makes sense not to cut away, though, because it will have a lot of handling.
