This particular free tatting pattern has both a video available at YouTube, as well as written out instructions below the video in the description area. Directly below is the video itself.
Legality precludes me from posting the written out version at this site, so I have instead posted a link to the YouTube video, where you can also find the written instructions.
This edging is incredibly dainty, and works well as an edging for handkerchiefs or pillow cases!
