This larger version of the original Quilter's Select quilting ruler is specially designed for  longarm free motion quilting work.  It is about double the thickness of a standard ruler to allow it to safely be used with your machine's ruler foot and ruler base.  There are two finger holes in the middle and a nonslip coating on the back for added grip and stability.

Ruler measures 3" x 12" and is 1/4" thick.

Also available in a 2" x 8" size.
