ronj;
I use three sets of brushes;
One set for acrylics - usually golden nylon,
don't use these types with oils or enamels as the tinners will effect them).
One set for enamels - usually sable hair type.
0ne set for oils - usually red sable and of a high quality.
Buy the best quality brushes that you can and look after them, it can be worth it in the long term.
