You can build shelves without using nails or screws by using dowels, glue and clamps. Start by cutting the dowels to the desired length and then drill holes into each shelf piece. Next, apply glue to one end of a dowel and press it into the drilled hole on each shelf. Finally, use clamps to secure the dowels in place until the glue has dried.
