A craft is exactly the same as art, just using different mediums. Crafts can convey meaning just the same as art. Crafts use many mediums such as clay, paper and textiles. This means that the crafts person possess great technical skills.
There is an element of 'craft' that is purely decorative. This also requires skill. There are imposters in all fields; it just seems that this type of craft has overshadowed the true craft movement.
Everyone has a different idea of what 'Craft' means. For some it's about making unique things by hand. Others see it as a continuation of traditional practices and techniques. Or it can be about experimentation, innovation and change, depending on your point of view.
