Clay bricks are affordable, timeless and durable. They can be laid in a variety of patterns and come in a range of colors, from red to buff to blue/gray. For paths and patios, bricks must be frostproof and hardwearing.
An even more economical alternative to brick is concrete block, which comes in a wide range of sizes, shapes and textures, and can be dyed to almost any color. You can also buy blocks set on a fabric backing (\"carpet stones\") or molded into a slab for easy laying. Bigger blocks can easily take the weight of a car and are ideal for driveways.
