Well, if you are willing to let someone else do the actual quilting (which takes care of sandwiching, pinning, and hand quilting or tying), you can make A LOT of quilts. Depending on your pattern, of course, but with a Disappearing Nine Patch type pattern, a large quilt top can be assembled in a couple of days--when you retire you will have all day to quilt and your production will increase dramatically.
Happy Quilting. :>
