The best way to build shelves without using nails or screws is to use dowels and glue. You can also use brackets, braces, and clamps for extra support. Make sure you measure and cut all the pieces accurately before assembling them so that everything fits together properly. Finally, make sure you sand and finish the shelf to give it a professional look.
