I was listening to the radio while sewing today and one of the commercials was about a tool they call a Center Ruler.
I had never heard of one, so I had to look it up online. The commercial mentioned it works well for quilting, which is what caught my attention. I'm including a link to a website so you can see what i'm talking about.
Does anyone use one or even heard of one?
