Doors and Windows - Winterizing my screened porch

I live in Texas so we don't have severe winters, but we have a large porch that is screened and we have a kitchen on one end of the porch. We use the porch all year for entertaining; however, there are some cold days that makes us head inside where it is warm. I would like to put up some type of decorative shade or material that would keep out some of the cold and allow me to put heaters on the porch so that I can use that space for entertaining in the winter. Do you have any suggestions?

My BIL had some clear plastic covers made that snap on with those 1/4 turn boat snaps, for his porch. We live where it gets considerably colder, so he uses those to extend the useful seasons for the porch. Also protects the furniture during winter.
