What paint brushes do you use to create different effects?

Over the years I have used some of my worn brushes to create different effects, but to help students I have created a specific group of brushes, so that when I demonstrate one of my techniques the students can have the same brush. This group of brushes can be found on the Rosemary and Co website . Within my Online Art School tutorials, I demonstrate the use of each of these brushes. For instance, I often use the short white ivory brush to achieve foliage. While a tree and texture brush can be used to add a glaze to an acrylic base in preparation for the details to be applied on top of that in oils. I often use the rigger brush for individual blades of grass or leaves on trees. The same brushes can be used for many different effects in the paintings.
