Stipple pattern:
Our painters and decorators say that you should make sure your stippler is “charged” by being slightly wet and then brush a little of your mixed up Artex on to the rubber tassles on the underside of the stippler. It is these tassles that will be patterning your ceiling. Use the Artex stippler to create this pattern by lightly pushing the rubber tassles onto the texture you have laid on to the ceiling, and when you pull the stippler off the ceiling you should be left with the stipple pattern, you should be able to create this pattern fairly fast by lightly “bouncing” the stippler on and off the ceiling, (use a larger stippler for this pattern if your ceiling is very big).

If the tassles of the stippler get too clogged up with the Artex to work effectively shake the excess off over the bucket in a sudden “jerk” movement, this will remove a lot of the build up and free up the tassles. 
To create a margin around the outer perimeter and around lights or ceiling roses, use a clean damp 1”paint brush, and lightly create the margin, don’t push so hard you remove most of the Artex from the ceiling though. 

After you create your margin , our painters and decorators say to use the 1” brush just to revove excess Artex from the wall if you have hit it with your roller while “laying on”, and rinse the excess artex out of your brush by using the clean water bucket if the bristles become too clogged up.
