Welcome !
Bright brushes are the same shape as flat brushes but have shorter bristles.
Filberts will create softer more rounded strokes because of their shape.
Flat brushes allow the artist to spread paint quickly and evenly over a surface.
Round brushes are useful for detail, wash, fills, and thin to thick lines.
Short Filbert provides a stronger spring than the regular filbert and has a similar to flat shape with rounded edges.
