No-Crayon and No-Water color Ruling

I hate it when my kids do painting with crayons and water color as this would spell w-o-r-k for me. Each time crayons are used, crayon dust would get stuck on our plastic table cloth, floor and under their finger nails too. Just the other day, rascal #2 caused a big mess on the plastic table cloth after an hour of coloring with crayons. She was coloring a Mother's Day card - project from her school teacher.  Her finger nails were spared from vigorous brushing and washing as I instructed her to wear a pair of disposable rubber gloves. But the table cloth needed washing and after a wash, the prints on the table cloth faded. It looks like I would need to go through some spandex table cloths selection to get a replacement table cloth. I have previously imposed a NO-crayon and NO-water color rule in the house but it seems quite impossible to enforce this ruling when the kids keep getting art homework from their teachers, sigh!
