I use vinyl tablecloths for everything, backdrops, picnic tables, etc- and I save them from year to year. If your tablecloth has wrinkles in it, you can toss it into your drying on a low heat setting with a damp (wrung out) dish towel.

It only takes 2-4 minutes and you have to watch it because they can and WILL melt if you leave them too long. Remember that you NEED the damp towels to raise the humidity in the dryer- it's what gets the wrinkles out.
