The walls are separated from the base plate with a craft knife. They can then be shaped with hot air or hot water. For this, bring approx. ½ litre of water to the boil. Then pour a thin stream over the desired spot for about 30 to 40 seconds and bend the wall immediately into the desired shape. Keep the wall in this position until it has cooled down. The walls can now be primed with a light-coloured Acrylic Paint. They are then individually coloured using the paints from the Nature Paints Set. To better accentuate the structure of the wall, the perfect result can be achieved with white or light grey paint using a dry wiping technique. Now the walls can be installed.
