To most people, the quintessential quilt design is the block known as Log Cabin. The versatility of the pattern, both in terms of individual blocks and in the enormous number of ways in which books can be put together, or set, has given Log Cabin a unique place in the quilting world. Its origins are ancient, its traditions are long-standing, and its modern interpretations are widespread. The secret of Log Cabin lies in its simplicity. In its most basic form the block consists of a central square around which are stitched strips of fabric of uniform width. These can be arranged around the central shape consecutively or they can be alternated on opposite sides, and the key to making an effective Log Cabin design is the way in which the colours - lights and darks - are organised. However, much of the enduring fascination of Log Cabin is in its infinite range of variations. Different widths of strips can be used. The centre can be any straight-sided shape. Shapes can be added at the ends of each strip to create additional, secondary patterns within each block. And again, the choice of colour values - the juxtaposition of darks and lights - is crucial to the overall design.
