I would go and check out for any used photo rods that are used in displaying quilts. You can see one in the photo on the far left. They are adjustable width size. Have your display pre-hung Like in the photo you posted) so when you get there, all you have to do is attach the top item to the frame. Then have a small folding table and chair sitting on the side as suggest above. People will come up and compliment you on your workmanship. Always wanted to put out a used tuna can out for tips.
