I have been using the inner bevel more after seeing it being used on other things besides frames but don’t remember where I saw it. Sorry!
For example, I used an inner bevel on the title of this layout (Alice) instead of a drop shadow. And, on the April layout, I used it on the triangles instead of a drop shadow. I’m really liking this effect. I usually use Bevel #1 or #2 and vary the width from anywhere between 8 and 12 depending on what I’m using it on.
