I’ve found that large disposable medical pads like these are really handy to use as small dropcloths. I use them to protect my workbench or table when painting, staining, gluing or doing other messy close-up work. I also use them to protect the floor around the temporary litter box when my son’s cat comes to visit. They’re reasonably cheap, less than 25 cents apiece in largish quantities.
Why I wish I didn’t know about this: I started trying them for various tasks when I ended up with a large number left over after my wife died of cancer, before which they were being used for unspeakable things I’d rather not remember.
