I could write a whole post on wood species as each species has unique characteristics and traits. But, one of the most common types of wood used in DIY projects and furniture building is pine wood (a softwood). Pine is an affordable and readily available option at your local home improvement store and it comes in many sizes. I highly recommend using pine for beginner woodworking projects. Then, as you improve your skill, try working with some different wood species!
When cutting full sheets with my circular saw, I use plastic shelving units as sawhorses. The height is just right and by using three of them, I can make cuts in any direction and the plywood is fully supported. And because the shelving units are made of plastic, I can cut right into them without worrying that they’ll damage my saw blade. Plastic shelves are available for $20 at home centers. — John Tinger.
