Here's how:
1. Use a paintbrush to apply a coat of plaster pink exterior paint to the outside of the pot. If necessary, applu a second coat when the first coat is dry.

2. Use angled fitch brush to paint copper metallic water-based paint around the rim of the pot and about 5cm down inside it. Leave to dry thoroughly.

3. Mix a small amount of strongly coloured glaze: add just a squeeze of burnt sienna artists' acrylic colour to about 10ml of acrylic glaze and mix together well with a brush.

4. Use a paintbrush to roughly paint on the glaze. Clean off any glaze from the dry copper rim with a damp cloth.

5. Holding the pot from the inside, take a pad of scrunched-up cling film and gently pat and roll it over the wet glaze, creating a crazed effect over the whole surface. Allow to dry thoroughly overnight.

6. To make a glittery top coat, mix a little sparkle dust into some satin arcylic varnish and use a varnish brush to paint it over the crazed surface, avoiding the metallic rim. The varnish will dry clear. For added protection, seal the pot with a coat of satin polyurethane varnish.
