If you look in a current quilting Magazine, they show a portable sewing table that folds flat when not in use. Here is the web site www.seweziusa.com. Iam thinking of getting one to use in our motor home. Hate using the dining table because I always have to move stuff when it is dinner time. My girlfriend's daughter has one to take to class and camp and loves it. Just a thought gives you another option.
