Oil Painting Brushes

Having good quality brushes is important. While a good quality brush will not make you a better painter, a cheap brush will only wind up frustrating you. When you use cheap brushes you will see why. Cheap brushes have a tendency to shed hairs that get stuck in the oil paint, which is extremely annoying. Good quality brushes should have stiff hairs and snap back into place when you run your fingers through them. They should be well crafted and sturdy.
You do not need that many brushes for oil painting. I personally only use two types of oil painting brushes: flats and filberts of various sizes. I do have a few rounds and a fan brush on hand, but I almost never use them. I would also recommend that you use hogs hair brushes as opposed to the softer synthetic hair brushes. The synthetic brushes are just too flimsy to handle the oil painting medium in my opinion.
Cleaning your brushes is important, so don't be careless in this area, especially if you are working with high quality brushes. Many artists recommend turpentine for cleaning brushes, but I simply cannot bring myself to use this stuff. I use a much safer brush cleaning product called "The Masters" Brush Cleaner and Preserver.
I clean my brushes right after a painting session with this product and it works wonderfully. It may take some time to really get your brushes clean, but it is worth the effort. If the brush cleaner does not remove all of the paint, then I use a bit of odorless mineral spirits. I find this a much better alternative to turpentine.
