Cut strips of plywood with a bandsaw. They should each be as long as the desired table leg, and two inches thicker. You want as many as needed to create a block two inches thicker than the finished leg.
Brush wood glue onto the surfaces of the plywood, and clamp the plywood strips together into a solid block.
Wipe of any excess wood glue with a paper towel. Allow the glue to dry for the time recommended on the bottle.
Sketch the front and side shapes of the table leg on the wood block with a pencil.
Set the guard on a bandsaw slightly higher than the height of the block.
Cut out the table leg using a bandsaw, which allows you to make curved cuts. You only need to cut two sides: one for the leg's front and back, and another for the right and left sides.
Sand the table leg with 80-grit sandpaper. You can completely round the shape or just remove any rough edges as desired. Sand the leg again with 120-grit sandpaper to refine the surface and then again with 180-grit and 250-grit until you reach the desired level of smoothness.
Paint or stain the table leg as desired.
