Select Stable Wood

You are probably may want to choose the most stable wood especially when you are creating good furniture or woodworking hand tools which require great stability such as try squares, straight edges or hand planes unless you want to have a figurative grain pattern on your furniture. 

Use stable wood on the other parts

You have to consider that wood moves when it dries and also when it comes to change in seasons and location like humidity and temperature. As humidity rises wood does expand in width even though it does not really get longer. It is a perfect idea to use a stable wood on the other parts even if you are using a perfect grain pattern on part of your woodworking plans. Usually, the panels have more decorative wood or less stable wood, but the stiles and rails which are parts of the frame are usually very stable straight grained wood.
