Does anyone out there have a clue why they can't be found any longer? (Oval) Especially the flannel-backed vinyl ones for households with children? (Usually were at Walmart, Target, etc.) I have seen only a very few linen ones but they are also extremely scarce, and please don't direct me to a high-priced store, I can't afford it. I would make them but the fabric doesn't come any wider than 54 inches.
