Painting for many people is usually a monochromatic affair and only those who are adventurous seek to play around with colours or decorative techniques. You need not use white or a single colour on all your walls and though finding colours that work together may be a task, you may choose to work with a given range of colours then differentiate the appearance of walls by using decorative paint techniques.
You would obviously create better decorative paint techniques if you are naturally artistic but sometimes even playing with shades of colours would give great effects. Decorative paint techniques add a touch of class and reduce the monotony of monochromatic shades.
There are a number of techniques that can guide you and they include sponging and stippling. Soaking up a sponge in paint and then creating random patterns by patting the sponge on your workspace could give unique results. Sponging may be used best on some sections of the walls especially in rooms where you desire to achieve a playful mood. Stippling involves painting in small strokes or dots and it allows you to coordinate two sets of colours appropriately. Think of how boring black paint on the bottom half of a wall and white paint on the top half would look and compare with how interesting a polka dotted space would look.
Paint techniques are versatile so you do not have to stick to pre-determined techniques and you can get inspiration from virtually anything. Sometimes even the paint that spills as you work may form an interesting shape. Rag rolling and paneling are other common techniques that you may want to explore. Decorative paint techniques generally give you a chance to get in touch with your artistic side and you can try as many weird patterns as you like until you find one that suits you best.
It would help to remember that the decorative techniques you use will depend on what you use the room for. You may want to stick to simple decorative patterns for formal rooms but you can add a touch of colour for playrooms or living rooms to inspire liveliness.
