Love how it helps
I have set this up on my white Viking after watching the tutorial video. It adheres beautifully to the machine, not so well to my customized wood sewing table. A little painter's tape rectified that problem. I purchased a second Clearly Perfect Angles to use on my Featherweight. OOPS! The gridlines disappear into the black background. I found the easiest way to get the "hang-of-it" was to mark one square the old-fashioned way and then figure out which gridlines to follow for that size square....
