When you say 1/4 and 3/4 inch wood, do you mean plywood with mahogany veneer (or whatever kind of veneer)?
Or something like 1 by 4 joined together, or wainscoting?
If you don't know the terminology, perhaps a pic similar to what you are going for, I will be able to point you in the right direction.
