Hola Carol. It costs $350 pesos to get an umbrella cover made here in LM. I don't know the cost for other uses. Sunbrella is the best material and unavailable here on the coast.
I would love some myself and between an 84 lb man or a roll I would go for the roll, especially a nice cobalt blue one. However, I don't know if anyone else would concur with me as $350 pesos is still a hefty sum. For awnings I think it would be great and the price, your contribution, might make it right. Cruz
