I bought a GoLite Utopia a few months ago and have been trying to get a floor for it since then. It seems they've simply sold out of them. I don't own a sewing machine but I'd like to get a floor for this thing. I can see myself ruining yards of SilNylon. Is there a guide somewhere on how to replicate a floor that could be modified for this tent or does anyone know someone out there that would custom make a bathtub floor for me?
