I do wish we had a different name for the sewing-all-three-layers-together aspect of quilting. It would make it easier when looking for things online, or explaining the process to non-quilters. I imagine this lady makes tops but does not quilt them, while her mother does quilt them. (But that doesn't mean she also makes tops. Such confusing terminology.) I suspect (but don't actually know) that early quilt-makers called making the tops piecing, or applique, and only used the term quilting to refer to sewing the layers together. But since the final result is a quilt, over time we've used the term 'quilting' to refer to anything related to producing a quilt. Just a guess.
