I go to Michaels and HobbyLobby for paints and brushes. I use Delta Ceramacoat paints and Royal Langnickel Majestic brushes. The paint is specifically designed for nonporous surfaces unlike most craft paints. I used to use the expensive miniature paints such as Citadel and Vallejo, but you can get 4 times the paint and 1/2 the price from your local craft store. The brushes keep their point very well and still have some nice spring to them.
