1. To paint the pine panel, mark horizontal lines at 300mm intervals, then centre a strip of painter’s tape over each line. Apply the lightest colour first then wrap the roller cover in plastic wrap to remove it from the roller, and wash the tray. Put on a new cover to apply the next colour, then repeat, changing the cover and washing the tray to apply three coats of each, leaving to dry between each. Remove the tape when the painting is complete, holding the end at 45 degrees to the surface to pull it off.
2. From the numbers, choose 14 zeros, eight ones, two each of four, five and six, and one each of two, three, seven, eight and nine. Put them on a drop sheet and use the small brush to paint the face and edges white; leave to dry.
3. To paint the ruler, from the base, mark 10mm intervals along the left edge. Paint a white line 5mm wide x 10mm long on each mark, skipping the 50mm intervals. At every 100mm, make the marks 10mm wide x 15mm thick.
Try it: Choose bright, engaging colours, but avoid anything too dark, as it will make the names and dates hard to read
4. From the base, arrange numbers from 40 to 160, positioning them in line with
the omitted 50mm intervals. Apply adhesive to the backs, position in place and leave to dry.
5. On the back of the height chart, measure 300mm from the top to attach D rings on either side with the supplied screws. Measure and mark 400mm from the floor, position the base of the chart against this to mark the corresponding position of the D rings, install the wall fasteners and hang the chart, using a spirit level to check it is straight. The base of the chart should sit exactly 400mm from the floor. Safety tip: check the weight of the chart and buy the corresponding anchors for your wall.
6. Use an oil-based permanent marker to write names and dates directly onto the chart.
