Greetings Marilyn and Ron,
Years ago we had a traditional house, and even back then it was tough to find old fashioned moulding. We ended up stacking 2 pieces of wood together and it looked great. At the base was "brickmold" (a simple, thick profile) and put a layer of trim (a style we liked) on top of it. We painted it in gloss eggshell color, and it looked great against hardwood floors.
This really looked good--but I've seen other people use a similar arrangement but do even more with it. For example, they might put a 1x4 between the brickmold and the top trim. Or a piece of contrasting hardwood between in a natural finish. Awesome looking--thought perhaps a bit 'much' for a farmhouse.
It was a good solution for us: easy to find, and not all that expensive. It also worked great in our case as we were trying to cover up carpet tack holes near the edge of the floor, and the brickmold was wide enough to make this work.
Anyway, just something to consider. Keep us posted, and good luck!
