All this time I’ve been thinking the rabbet (picture frame) measurement is how far it extends over into your picture. This morning Denise from Just Quiltin sent me an email and said “You are so dumb!” No, that’s not what she said. She was much kinder but she explained that . . here . . I’ll just copy what she said so I don’t screw it up.
I think you are thinking about the “rabbet depth” measurement wrong. So for instance in that blog post you say a frame has a 9/16th” rabbet depth but that’s not the amount it overhangs your stitching on each side. The rabbet depth is the measurement from top of the rabbet to the bottom of the frame (flush with back). So where it comes into play is if you have thicker artwork – like say you added two layers of foam core instead of one — that might make it too thick for your frame so it would stick out over the back of the frame and you wouldn’t be able to shoot your points into anything to hold it in place.
She also sent this:
That makes so much more sense than the way I was thinking about it.
Thank you, Denise, and sorry for anyone I confused.
