How can decorative dots of equal size be made with acrylic colour?

Correct answer: By using an equal paint load and applying equal pressure

The governing concept is controlling repeated marks through a consistent paint load and pressure. If approximately the same amount of acrylic colour is placed on the tool and the same pressure is used each time, each dot spreads by a similar amount and appears uniform. Therefore, option B is correct. Changing brushes introduces variation, excess water can cause running, and folding paper does not control dot size.
