I had a 12x14, it was large enough for three with a stove and table. Nice to eat out of the weather. I never had a problem with embers, but tore the mossy netting. Duct tape to the rescue . Canvas is easy to repair, unlike nylon or plastic. It requires rewaterproofing after a few years, though.. And it is does need to be dried. So a take down in the afternoon on a dry day was aimed for.
