  1. For an instant preview of what your colour choices could look like in your room, download the free Visualizer app for your android or ios device.
  2. Narrow it down to a few shades.
  3. Apply your background colour first, using a roller to cover a large surface area. Create M and W shapes as you roll to achieve an even coverage. Once the paint is completely dry (this can take from 2-4 hours), you’re ready to start your arch.
  4. First, cut a long length of string and attach keys to one end.
  5. Use masking tape, stick the string to the wall at the right height for the side of your arch. Cover the string with chalk and quickly pull string towards you and release against the wall to make a chalk-line that you will use as a guide when masking. Mask along this line with tape.
  6. Using your spirit level create 4 points creating your desired width and height size. The width at the top will create the base width for the arch.
  7. Measure the gap between the two sides of the base width of the arch and mark the mid-point.
  8. Attach a pencil to the end of a length of string . Pin the string at the mid-point between the two points so that the pencil reaches either point of your base width.
  9. Draw a semi-circle to form the top of your arch, then carefully paint the outline using a paintbrush. Fill in the rest of the arch using a roller.
  10. Gently remove the masking tape while the paint is slightly dry.
