I don't know whether I'm terribly old fashioned or a super-green hippie or what, but I love me a nicely set table with pretty cloth napkins and placemats or a tablecloth.
While upholstery samples might get a little bulky for a tablecloth (my mom's quick and easy tablecloth is just two yards of 54" wide fabric with a rolled hem), they make super placemats. I had some scraps in my pile that were about 12 inches by 24 inches. I used a placemat my sister brought me from Guatemala (that's it, on the left in the photo) as a guide, but about 12 inches by 17-18 inches looks great. Then I used the leftovers to make some pillow covers (info coming later).
