For me it depends on the quilt and why I'm making it. I have completed a lap quilt in 24 hours for a co-worker whose daughter was killed in a car accident. It was a simple large floral block with sashing and corner stones, so not a lot of sewing. I have one I've been working on for over 2 years and it is no where near finished. If I dedicate myself to just one project I can usually finish a lap quilt (about 50x65) in 1-2 weeks.
