JAN says: "This is the PERFECT tool – IT REALLY WORKS!"
From the designer:
"The Perfect Piecing Seam Guide is my first attempt at a notion type solution for a quilting problem….I have been teaching for several years now and one of the biggest issues I have noticed in my classes is that pesky quarter inch seam allowance!
It is so very elusive for beginning quilters and can often be a problem for just about anyone. If you change machines or even go from one 1/4 inch foot to another, there can be a difference in your results.
This little ruler has a laser line with a needle hole that is a SCANT 1/4 inch from the edge. You simply mark your machine with a piece of tape or a sticky note. You can be consistent from machine to machine."
