Liner No.2
 
A super-thin long bristled brush - also known as a rigger or a script liner.
This brush is best for fast, fluid, loose, long, swirling lines (à la Erica Walsh), adding a fine, delicate
element to a design. It could be used for whiskers (though I prefer the dagger for this). You can
also twist and slide it to produce more mystical lines (à la Monique Lily).
