After looking at all the other posts on here I decided to start my own blog. Attached are pics of my coffee table central n scale layout. It started with a 3 by 3 coffee table from a yard sale. I think its an IKEA model but I'm not sure. It measures 37 inches square and the layout itself is 36 inches square. 1/2 pink foam was glued and svrewed to the table top. As there are no turnouts or grades I cut risers for each progressively taller loop from extra foam. The roadbed is also pink foam joined at the seams with foil tape.
