A box is one of the most basic wood-working projects there is. It is also one of the most versatile. It is the basis for frames, containers, shelves, and more.
Most of these DIY projects are variations of the basic box form. It is a project worth practicing often. Two of the most common applications for an artist are illustrated here, 1) a canvas stretcher and 2) a wooden painting panel. All of my projects use primarily recycled or leftover materials. A box can be simple or complex, large or small. Check some other posts for examples.
Start by determining the size and type of box you would like to construct. Cut the four sides to size. You can use four equal sides, or a rectangular form that is long and thin. The joints can be beveled or straight. More advanced joints include dovetail. Assemble the sides together and then attach the bottom or base of the box. The top can be hinged or fitted.
