How to Cover a Garage Sale in Rain and Thunder? - tents for sale

Please help ... I have a flea market tomorrow, "flea market in the community" and I noticed that the weather network means 100% chance of rain and thunder. I need a way to cover products that I sell, what does not get wet. I have no tents or umbrellas. Reasons not to answer "for another day.

Thanks
