I used three spindles to make 9 candle sticks and 9mm mdf to make the base and tops. The bases were 4cm by 4 cm and the tops were 2.5cm by 2.5 cm. I cut these using my miter saw. They were all scrap wood pieces left over from another project.
Make sure you sand the edges of the mdf and any jaggered parts on the spindles to make for smooth painting.
