When I saw this idea at Our Daily Obsessions, I knew I wanted to make it for my father-in-law for Father's Day. I tried to find plain white dinner napkins at a couple stores but had no luck, so I decided to make the napkin too.
Afer I made the tie napkin, I thought it might be fun to make a bow tie one as well. The bow tie napkin is smaller - finished size 17"x17" and the tie napkin is finished 21"x21". I just traced a tie to get the shape and length. But I freehanded a bowtie.
I google'd how to make the napkins so it would have a polished and "non-homemade" look to it. I used a combo of a couple different links to get the clean corners. I didn't write down the links I used, but just google "how to make a dinner napkin" and you'll have a few choices. Here's a close up of the corner from the back side of the napkin.
