Once you're done with your collage, select your layer with the mask, then Ctrl-Right Click to create a selection based on that mask.
Then go to Select > Modify > Borders and create a border around your image. Fill it with black and set that below your collage. Or just select your final image (assuming no background), and Select > Modify > Borders to create a border and fill that with black.
Edit: Or I guess you can just Layer > Layer Style > Outer Glow or Stroke.
Ok so I tried it and the layer with the mask is highlight blue, but when I Ctrl-right click I get a window say backgrou, select similar layers............... Did I do something wrong?

Or Ctrl + Left Click on the mask to create/load the selection. Click the picture icon for the layer so that you are working with the image and not the mask. Then Right click inside the marching ants selection area on your image then choose Stroke from the pop-up menu. (or Edit>Stroke) Chose the color and pixel width as well where on the selection you want stroked. I.e. Inside, Centered or Outside the selection. Click Ok, and then Ctrl D to deselect.
Looking at your mask you might also need to Invert selection after you ctrl +click on the mask to load selection. (Select>Inverse, or Shift+Ctrl+I) That way the selection will be of your collage only.
ALright Ctrl-Left click on the layer mask selected the entire outside of the document along with the shape of the layer mask. Then I reclicked on to the white document just to the left of the layer mask. Now when I right click within the marching ant the window pops up but everything is greyed out. WTF? But I can go Edit: Stroke and it will work but the stroke doesn't appear until I do Center or Inside, outside doesn't work. Sweet It works, but I have to go back and mask out the outside border stroke not a big deal, But before I finalize the stroke I need to go in and clean up the layer mask, need to make all the lines straight and not bumpy.
Thanks a bunch guys, Now I know in the future.
