I am starting out with a smallish end to end layout.
I previously has a 6m by 3m round the wall layout on which I used cork tiles as underlay to give the rails that raised look.
However, with this current layout it is going to be a TMD and so raised track might look a bit odd.
I'm thinking of buying 3mm fibre underlay and laying over all of the baseboard.
Does this sound like a reasonable plan? I don't really want to lay directly onto the ply baseboard.
