What is Brush?
[[File:hairbrush.jpg|thumb|242px|A hairbrush]] A '''brush''' is a tool with [[bristle]]s or wires or other filaments sticking out. There are many kinds. Most brushes have a long part at one end to hold (the [[Handle (grip)|handle]]), on the other end from the [[head]] that carries the bristles or filaments. We use brushes for [[cleaning]], making [[hair]] look good, [[painting]], and other purposes. ==Brushes for cleaning== Many kinds of brushes are made for cleaning, for example toothbrushes or brushes for cleaning floors. ==Paint brushes== We use paint brushes for putting [[ink]] or [[paint]] on [[paper]].

This is why many artists like them for painting large things and for color washes. * Flat: These are good for spreading paint. * [[wikt:fan|Fan]]-shaped: These mix paint well. === Brush care === * Clean paint from brushes after you use them. This is very important for [[Oil paint|oil]] and [[acrylic paint]] because when the paint is dry, taking it off can break the brush. * Never leave brushes in water (etc.) with the bristle end down. This is because the bristles can change shape. === Sizes and materials === We can
