Searching for something
 

I'm searching for something that I don't know what it's called. It's a clear vynal mat that lays on the bed of the sewing machine and goes under the pressure foot. It has sewing lines so you can sew your half squares by using the printed lines on the mat.

A couple night ago I saw a video about it but now can't find it. Does anyone know what it's called?

The angler.

There is also clearly perfect angles which is similar but a little larger

Thank you, thank you, yes the Angles is what I was searching for.
