Is there a difference between oil paint brushes and acrylic paint brushes?
The difference is not natural vs. synthetic, but texture. Acrylic brushes are smoother, and oil brushes have rougher bristles. Good acrylic brushes can be sable or a synthetic equivalent, sometimes called sabeline. They could also be made of nylon. Oil brushes are usually made of hog or other animal hair. Some brushes can be multi-purpose, especially if you thin down oil paint as an earlier poster said, but you shouldn’t use very soft brushes with oils. Oils actually are rougher on brushes than acrylics.
