I am somewhat of a traditionalist. Many pieces of furniture 75+ years old have stood the test of time. Most of these pieces use tried and tested methods of construction. Properly cured wood that is stable won't crack or check, won't warp or bow.
Today it is quite difficult to find material that has been cured in the old-fashioned way, so one must employ sound methods of construction to offset the shortcuts of modern curing practices.
I buy my stock oversize, then straighten each piece and thickness it, generally to one inch. For me, a piece of 1"x, which is actually three quarters of an inch, always looks like a piece of wood from the modern era. It rarely performs the way it should and when it comes to pine, it's best kept out of sight.
You should know that material is a fraction of the cost of a project; if I have to fight with poor quality materials--well, let's say I'd get upset. Like anything else, you get out what you put in.
