First, how rude. I agree with CKCOWL. No specific amount. Juggling various things throughout the day, and one thing might also be a nap! On weekends I usually will do 3 or 4 hours at a stretch. And I have many piles of projects in various stages. When I retired I honestly thought I would spend at least 4 or 6 hours a day quilting. I guess I need more discipline!
