1. Cut a piece of cardboard 24 cm long, with 14 cm width at one end 9 cm at the opposite end.

2. Cut two strips of polystyrene (height 18 cm – width 3 cm – depth 1cm).

3. Attach the polystyrene strips to the cardboard with glue.

4. Dig 8 grooves in the polystyrene with the scalpel leaving regular spaces in between. The grooves on one strip need to correspond exactly to the groves on the other polystyrene strip as the pencil will need to slot in.

5. Paint the polystyrene strips and the base and let I dry before moving on to the next step.

6. Make sure your pencils are different in colour and size; then start slotting them in the polystyrene grooves from the longest to shortest alternating the pointed side.

7. Once you are happy with the positioning of the pencils attach them with glue.

8. Put a heavy book over the top to help the pencils to stick better to the glue in the polystyrene grooves.

9. Make two playing drums with two wooden kebab sticks and two wooden beads.
