Felt-tip pens, with their rigid tips and lurid colours, used to be for children. Now, felt-tip pens have a flexible brush tip and come in a range of carefully graded colours, from vibrant hues to subtle shades. These pens have resilient tips and free-flowing ink, and are always ready for use. This guide shows readers how to get the best out of brush felt-tip pens. They can be used to create anything from watercolour-style landscapes to intricated botanical studies.
