>   One of the many uses for plywood. --Photo by mtneer_man via Flickr   And yes ladies and gentlemen, there is more. I listed a few of my own disadvantages and advantages below.  Advantages:

Weight: A regular 4x8 sheet of plywood is much lighter compared to other types of wood. This is due to the layers of particle board that compose the sheet to give it ridgitity. Less weight means less stress on the flooring, siding, or whatever application you may use it for.  

Pliability: Plywood can be bent or shaped much easier than other materials. It has the ability to maintain its strength while bending without splitting or warping.  

Various sizes: The standard size of a sheet of plywood is 4 feet wide by 8 feet long with a 1/2 inch thickness. And the sizes expand larger and smaller from there. Most hardware stores will be able to find you a sheet in the exact dimensions that you are looking for.

Disadvantages:

Weather: One of the downfalls with plywood is its susceptibility to accumulate moisture and become weathered. This is, of course, unless you buy plywood specifically rated for outdoor use.  

Appearance: You obviously won't use plywood to finish your kitchen cabinets. It's rather ugly, and traditionally only meant to provide structure and stability to your projects.

Can't be milled: Since plywood is made using layers of particle-board and wood, you can't mill it for a thinner cut. However, the different sizes and thicknesses offered at the store should solve this issue.  

In the end, I'm grabbing at straws trying to find any flaws with plywood here. As long as you do a bit of research before shopping for materials, you will have no problem finding the correct piece of plywood for your next job. Now go grab a couple sheets of plywood and start working on that project.
