Select the type of wood to make your table. White pine is a versatile and inexpensive hardwood that can be stained light or dark to match your decor. Clear white pine is a bit more expensive, but free of knots.
Purchase the wood at a local lumber yard or home improvement store. Select nine 2-by-4 boards for the table top. Choose each piece individually. Look down the length of the board, making sure it is straight. Buy 6-foot-long boards and skip having to cut them to fit.
Lay the table top boards on a flat surface parallel to one another. Put most attractive surface on the top.
Cut the 12-foot-long 2-by-4 board into three equal pieces. These boards will hold your table top together from the bottom. Lay these cross-boards across your table top boards and screw them together with wood screws. Make sure there are no gaps.
Cut the three 1-by-6 boards in half, so they are each 36 inches long. These are your legs. (One 36-inch piece will be leftover.) Pre-drill holes in the cross-boards where you will set your legs. Screw in the legs by attaching two legs at both ends and one directly in the center of the table.
Sand all of the surfaces until smooth and ready to stain.
Brush an even coat of varnish on all surfaces. Let the varnish dry for the recommended amount of time. Repeat this step until the desired finish is achieved.
