Okay..

I've been working on a series from my recent vacation using several reference photos of different views of the same area.

I'm pretty excited about them so far and had in mind that I wanted to put three of them together in what I think is called a "triptik".  I don't know the exact word or if there is a specific way to mount them ..

I had visualized sort of a staggered look so that the paintings aren't exactly in line with one another, but have the following questions...
1.  HOW do people "frame" or mount these paintings?
2.  Is there an expected protocol on how to lay them out.... staggered diagonal vs. in line... vs  up down up, etc.

I'm really asking for advice because I'm pretty much on totally new ground here.  The paintings are almost done, but before I photograph them I want to decide how to arrange them..

I'd love to hear what those among you who are more expert than I am have to say.

Thanks..
