This is a brilliant little gadget that helps keep my seams straight! Great product!

Ruler does its job. Obvious it was a return as it is very scratched up. I don't blame seller. Guessing that Amazon put it back on the shelf

The long side doesnt start at zero, its about 1/16 " too short, so cant use that side for measuring from the edge. The 45 degree line agrees with me, doesnt start at the absolute corner of the ruler. I was going to post a picture but i didn't have to. Look closely at the pictures the mfg has posted.

I am just an occasional sewer. Simple easy items once every few months /year/ whenever. This just made it easier for me so I didn’t have to relearn/reset . Fun little gadget .
