I redid the oval with an expanded aluminum from Home Depot (think it was made for a storm door or something) and the bottoms look like a gutter guard or something but close to oval look.
However, I'm interested in this whole package, though I think I'd like to buy a oval rim on ebay for $28 or so, do those aftermarkets work? Could I have them ship it to you and then pay you with paypal when you received it for the $98?
Is there a bit more of a close up of the actual mesh being used?
