To clean the brush, simply squeeze it gently to encourage more water to flow out, then wipe it on a tissue. Waterbrushes are useful for on-site sketching, together with a small travel watercolor set, as it eliminates the need to take a container with water. If your local art store doesn't stock them, many online art stores do. Various manufacturers produce waterbrushes, in a few sizes, and in either a round or flat shape. A slow, constant trickle of water comes down the brush's bristles as you use it, and you can get more by squeezing the reservoir.ДЄ waterbrush is ideal for using with watercolor paints and watercolor pencils, including lifting color directly from them. The two parts screw together and apart very easily. It consists of a head with the brush on it and a handle that's a plastic reservoir that holds water. (It's most obvious on a round brush, rather than a flat one.) A substantial belly on a round watercolor brush enables you to pick up a large quantity of paint at a time.ДЄ waterbrush is like a combination of a fountain pen and a brush. The belly is, as the name would suggest, the fattest part of a brush. The toe of a brush is the very end of the bristles, while the heel is where the bristles go into the ferrule at the end of the handle (not that you can usually see this without taking a brush apart). A decent-quality ferrule won't rust or come loose. Mop brushes, for instance, can have a ferrule made of plastic and wire. It's usually made from metal, but not exclusively. The ferrule is the part that holds the handle and hairs together and in shape. Most important is that they're firmly held and aren't going to fall out constantly as you paint. What bristles or hairs are in a brush is also variable, depending on what the brush is intended for. You're going to be using it a lot, so it needs to be comfortable to hold. What's more important than length is that the brush feels balanced in your hand. The length is variable, from really short (such as those in travel paint boxes) to really long (ideal for big canvases). The handle of a brush is most often made from wood that's painted or varnished, but it can also be made from plastic or bamboo. All the variabilities can affect your work. When choosing a brush, examine each part of it.
