After knowing your paintbrushes, this is another part that needs to know about Brush Hair and Bristles.
Paint brushes are either made from natural hairs or synthetic hairs. They are soft and stiff. For soft brushes are good for thin paint which helps spread easily on watercolour paint, as well as detailed work. As for Stiff, hard brushes are used in the thick paint when using a certain technique in oil painting.
Nature hair or a Synthetic hair better?
Synthetic hair are man-made of either nylon or polyester works very well with acrylic paint, but can be damaged for natural hair brushes and a large painting.
However, brushes for acrylics can be used for oil and watercolour painting. Natural hair brushes for acrylics unless you are willing to replace it often cause it may ruin natural fibres quickly when you keep your brush in the water with the chemicals when painting with acrylics.
The synthetic hair brush is cheaper than Natural hair brushes. A good synthetic brush is rugged, can maintain the shape well and easy to be clean.
I would recommend synthetic hair brush but at the end of the day is still up to you to choose and decide what brush suites you well for your artwork.
Note: Cheap brush may not works well and your painting might not turn out perfect.
