Brushes
The most valuable tools you'll ever own are your brushes. With the right brushes, you'll benefit in your art and learning. There are many types of brushes out there. Kolinsky sable brushes are considered the finest brushes on the market. But, quality is not necessarily costly. Personally, I prefer the relatively inexpensive Jack Richeson brushes. Naturally, we all have different views and need to use tools we feel most comfortable with. Try out several different brushes and make your own choices.
