To Paint a wavy line

1.First draw gentle curves lightly on the wall with chalk. You can wipe away the chalk if you don't like the layout and redraw until you are happy.Don't make the curves too tight as it will be difficult to bend the tape to shape.

2.Begin sticking the tape to the wall following your lines and coaxing the tape gently into shape around the curves.

3. Where there are little creases in the tape, flatten them down to stop paint from seeping under the tape

4. Paint below or above the line, always brushing the paint away from the tape rather than to into it, to stop the paint from bleeding under the tape. Also make sure your paint is not too runny.

5. Now if you wish, paint the other half of the wall and allow the paint to dry before removing the tape gently to reveal the design with a line between the two colours.
Use wider tape for a wider line.

You may still find some paint has bled underneath. You can touch this up with your original paint colour afterwards.
