The Bob Ross Floral brushes are made of pure, soft but stable bristles. Specifically designed to work with Bob Ross Soft Oil Colors, these brushes are perfect for painting tiny florets to big roomy petals. The Œë_í_í_Œ Floral brush can be used to apply background mediums and colors or to paint very large flowers. It is especially good for painting large double-wide tapered leaves, such as those of the Iris.
