"In one sitting"????
Well I really don't sit all the time. Lots of time I sit to sew and stand to iron and walk to the other stations. Then when I'm longarming quilts, I stand almost exclusively...except for breaks.
I've been known to quilt for 3-4 hours without a break.
Whether I'm sewing or longarm quilting, I'm working on one project each day.
