The majority of what I make are Art Quilts - made to go on a wall not a bed. They range in size from 7" X 8.5" to 5' X 6', so far anyway. This last year I've joined a small group in my guild and we have a challenge for each month - so those quilts tend to be much smaller than others I've done.
My largest quilt was posted in Pictures with the title "Fireworks Quilt blocks pieced". That goes thru the process of fmq it. Towards the end are complete pics. of the whole thing as well as the individual colored star breaks.
