Steve,
There is nothing wrong with a couple of loops. What I am mainly interested in is building model buildings and to have a couple of tracks run by. My room is only 14 x 12, so my space is limited, and my buildings are many. One thing I try to do is copy parts of another's plans, like the yard, and go from there. It is not easy for me either, and to be honest, I have no track laid as yet, I am just starting up again, and have been 'starting' for about 3 months now with barely a small piece of bench work up on one wall.
