I made six napkins, which took 2 yards of fabric (with a bit left over). Mine are 16 x 16," which for me is a good sized napkin. They didn't take long to sew, though I'll admit ironing out the lines for the mitered corners got tedious after a while. But the result was definitely worth it!
Here's a preview of my tablesetting--a bit eclectic, but I like it. :)
Anyway, I'm very happy with them and have already packed them up with the rest of my kitchen stuff. I can't wait to use them in my new apartment!
