I often find myself having to walk away from a layout that's not working for me, but it is rare for me to not go back to it at some point.
I actually find that sometimes leaving it alone (sometimes for weeks!) helps me to focus on where I want it to go. It's a little like doing a crossword puzzle for me, I often find that answers I've struggled with sometimes leap out at me the next time I go back to it.
So here's one I started and struggled with at my last crop, this is my gorgeous grandson Elliott enjoying what can only be a rare moment of sunshine!!
