I finished it. This apron took the most work, concentration and time of any I have made so far. It's no sewing masterpiece, believe me, but I'm proud of it anyway. I'm only a novice sewer after all. This was the first time I have ever used piping in a project. It's not what I would call easy, but it's do-able.
Here's a closeup of the front. . .
. . .and of the back.
Thanks go to Travis for his photographic cooperation.
What a guy.
