Yes, keep it simple. When I tell non-quilters that I have a longarm machine they usually have a blank look on their faces. I think they understand after I start at the beginning and tell them to think about all those "lines" that go across a quilt - that's quilting and that is what I do with my longarm. Non-quilters/non-sewers don't have a clue about what we are talking about.
Putting the top together is "piecing".
