I think some people call it a stitch-in-the-ditch foot. The blade follows the edge of the fabric and I adjust my needle to whatever distance I would like from the edge. Before I found that foot (I wish I had found it years before) I used the edge of the presser foot for the first round and one of the lines on the foot for another.

I hope this helps. Finding the right foot can make your life much easier.
