Curve master presser foot

[dfabbric]

So I have just discovered this great sewing foot that works on any machine, except Bernina. You need an extension.
The Curve Master Presser foot allows you to easily sew curves. Mine's in the mail.
Here's the video

Now I really want to try a double wedding ring quilt. Does anyone know any good patterns?

Have you received it and checked it out already?
I'm interested if it works as well as shown in the ad, when objectively judged.

I am embarrassed to admit this, but I've had the foot since September and have yet to try it out.    It seems like something else is always moving to the front of the line.  I bought it after the review on the Jaybird Quilts blog.  I'll try to do something with it soon and report back.
