You would like to be more creative, but paint brushes are your only expressive medium. You need a tool that will change the way you apply paint to the canvas for a unique aesthetic result.
Solution
To create more texture and make your painting, sculpture or other artwork more interesting you can use steel wool, like this:
Apply a large quantity of paint with your brush or by flicking it from a distance.
Use the metal scourer in a circular motion or in a direction that will bring you the desired result.
Allow it to dry.
Repeat after a few days if you want to improve or change it or make the texture more pronounced.
