This was easy......

I used a LR preset for this collage.  It was a drop and drag, click on the edges to resize, and walla....  it was done!
     Molly is in the L top, Abby was in the RT top and RT bottom.  The L bot is my bedroom, at 7 am, with the rising sun shinning brightly through the window.  This was easy and effortless, now that I know how the program works.  I will try a custom layout tomorrow.
