I recommend five brushes for beginners which should give you a lot of scope with your painting. It is important to have more than one brush and more than one brush type when you are a beginner. You may not want to buy many brushes but these 5 are the most useful in my view.
- Large flat brush
- Medium sized angled flat brush
- Medium sized round brush
- Small round brush
- Medium sized filbert brush
These five brushes will give you flexibility in how you paint and each brush can do a slightly different job. Another brush that is handy is the fan brush, this brush is fan shaped and ideal for light texture.
Most beginners buy a pack of brushes, this is often less expensive than buying brushes individually. Look out for a pack of brushes containing these five types of brushes. Starter brush packs are ideal for beginners but do make sure they contain brushes of different sizes, some contain brushes which are basically the same.
I would recommend synthetic brushes for beginners, they are less expensive than natural fibre brushes and are all-purpose which means you can use them for everything.
