You could hit it with a can of "hammerite" spray paint.It comes in a few colors & is made for metal applications.If You get the textured finish,it can help to cover any blemishes also.Good luck with the project

Thank You All. Before I read your responses, I had mocked up a 36" chair to check it out. It didn't grab me. Then I looked at a BUNCH of pins on my Pinterest account...funny, the shorter 36" chairs DID look odd. So, I txt'd her this am, told her I couldn't make it, but told her if she doesn't sell them to let me know. They would make great extra chairs for when the table is extended. Most of those type of chairs I have found are 36" in height. Although occasionally I do find a 40" set. I think I will hold out for either a larger set (dimensions and quantity) or maybe go with a totally different style of chair. Thanks again, you all confirmed what was already in my head. Bee

The trouble with making a fabric covering for a lawn chair is attaching it to the chair and getting a strong enough fabric to withstand the weight of a person sitting. They do sell webbing for chairs that can be covered with a cushion

The rental centers figure that a 5' round with 8 chairs needs at least 10' of space to be able to pull out chairs. Therefore, I would guess that a 6' round with 10 chairs needs at least 12'. The best way to lay out the tables and chairs is to use graph paper that has a grid on it. Then figure out how many squares equal a foot and go from there.
