As far as UFOs are concerned, I have my own definitions:
Pattern selected & fabric pulled, stored in a bag, box etc.- this is just maybe a quilt-to-be, or I might change my mind...
Fabric cut and I'm working on it - Top in Progress
Fabric cut but I haven't worked on it in "X" amount of time, where "X" is determined by whim, but usually around a month - UFO
Top done but not quilted - this is a completed top! Not a UFO!
Top Quilted but not bound - Back to UFO land...
