An eco-friendly, disposable area rug. What a great idea. I think I'm going to try that. I'll just sit in the middle of it while i work my way around the outside AND I can use it as a coaster while i work!

This is a really cute idea/instructable though. So many possibilities. Themed by magazine type, colour combinations for sports teams or even crafts for kids to make for their birthday party.

I think spraying a layer of waterproof gloss on them (especially if made of newspaper) might prevent the need to toss them each time a glass sweats on them. Newspaper ink smells pretty bad when it gets wet/dry/wet/dry.

Is there some sort of think, waterproof "rubber" type sealant that would make them even more durable (and skid proof!)?

I think Mod Podge would work well. I use it to seal wooden coasters. You can get it at craft stores.

Some sort of "thin" not "think" waterproof sealer. Fingers are faster than my brain.
