A fan brush is used for blending and can create multiple lines or dots in uniform. It is perfect for creating grass, producing a series of lines in one stroke.

The Graduate brush range sounds like a versatile and comprehensive option for students and hobby painters. Here are the ideal brushes for each medium within this range:

1. Oil Painting: For oil painting, the best choice would be brushes with natural bristles. The natural bristle brushes in the Graduate range would be the most suitable option for this medium. Natural bristles, such as hog or bristle hair, are sturdy and can withstand the heavy texture of oil paints. They have good paint-holding capacity and provide control and durability needed for oil painting techniques.
2. Acrylic Painting: The synthetic blends available in the Graduate brush range are specifically mentioned as great for acrylic painting. Synthetic brushes, typically made of nylon or polyester, are well-suited for acrylics. They are durable, easy to clean, and maintain their shape well even with the thicker consistency of acrylic paints. These brushes provide smooth brushstrokes and excellent control.
3. Watercolor Painting: For watercolor painting, a combination of natural and synthetic hairs is often preferred. The Graduate brush range offers blends of natural and synthetic hairs that are particularly suited for watercolor. Sable or squirrel hair brushes are popular choices for watercolor due to their softness, ability to hold a lot of water, and precise control. The blends in the Graduate range can provide similar characteristics, making them suitable for watercolor techniques.
   

   In summary, the ideal brushes for each medium within the Graduate brush range are as follows:

   • Oil Painting: Brushes with natural bristles (hog or bristle hair).
   • Acrylic Painting: Brushes with synthetic blends (nylon or polyester).
   • Watercolor Painting: Brushes with blends of natural and synthetic hairs (such as sable or squirrel hair).

   With the variety of blends, head shapes, and sizes offered by the Graduate brush range, it provides a good selection for students and hobby painters working with different mediums and techniques.
