Book excerpt: This creative and informative book explores the ways in which barriers can be used to add style and character to the garden. The first half of the book looks at boundary choices, from traditional fences, walls, hedges, trellises and railings, to screens and natural boundaries. The second section of the book looks at the finishing effects that can be applied to off-the-peg or existing boundaries to customize them with your personal style, add a decorative theme, or blend them in with the property and its surroundings.
