I am a only when I can’t find what I want type of sewer. That said the quality of the piping is wonderful. I tend more toward the creative and much less to the mathematical, so I was a bit surprised that the piping was the width of a piece of yarn. Not what I had hoped for but as there wasn’t a larger size, perhaps this is where the difference between cording and piping comes in??? Not sure. I quickly will add that it was so much easier to use than to make my own.
