"First of all, I love, love, LOVE my 12 Multicolored Napkins!
That said, here's a bit of advice for selecting cloth napkins... (in case you grew up in a paper napkin house like me):
Solid colored napkins will show stains, grease spots, and detergent marks like crazy!
Patterned napkins are much better at hiding small irregularities like those random darker "stains" that are obvious on solid colored napkins.
I've had these experiences with solid napkins from several different stores and in several different colors. Oddly enough, I think the white ones are actually the best at hiding these marks because you can bleach them. This rule might not hold for white napkins with pastel or lighter patterns printed on them. Most of our stuff is boldly colored.
That said, I still love the unexpected look of different colors around the table and am currently wishing for the multicolored cocktail napkin set to coordinate."
