So that's what I did, and not only did it cost a fraction of what I used to spend, the pieces are so wide I needed only one of the sheets I bought and the other became a table cloth. After using it for the week, I launder it, since it does get pretty yucky by the sinks.
For the past couple of years, I've said, that it's time to replace it. "Last year for these pieces." But then I pack them away and set them up again, like now. I used to have leftover contact paper which I used on the "peninsula," but that's all finished. I think I used aluminum foil last year. But this year I decided to cut up an old plastic Passover tablecloth.
Here are the pictures. Now I must get some sleep.
