Find a well-ventilated area to spray in – I would suggest a sheltered spot in the garden on a dry day.
Prepare the area you are going to spray in by laying down plenty of newspaper. Weight it down at the edges if you need to.
Start by priming your mache cone; use the white primer spray with light strokes, spraying about 30cm away from the cone in gentle bursts. Spray until you have achieved an even coverage, especially at the top of the cone.
Now it’s time to add some colour! You are aiming to colour about two thirds of the cone with your chosen colour – follow the same as you did with the primer, starting at the bottom and using gentle bursts to build up the colour. You want to create an ombre affect by building up lots of colour at the bottom of the cone, and thinning it out as your reach the top.
Leave your cone to dry for 15 minutes. If needed, touch up the colour on the bottom of the cone with a few extra sprays.
If you think you have gone too far up the cone with colour, use the white primer to spray from the top down on the cone and re-establish the white.
