If you are using ready to run track then Peco planning sheets - essentially full size photos of points - are available and are idea for this, and a lot cheaper than waving the real things around. Since my track will be made using SMP parts I've used the plans they supply with the point kits. A trip to the photocopiers has furnished me with a small pile, easily more than enough for a tiddler layout. One clever idea is to copy the right hand plan on to acetate and then flip it over to get a left hand version.
Initial thoughts involve the stupidly tight 36" radius Y-point playing a big part in the model but I have some others available just in case I can get away with them.
