Craft to me is exactly the same as art, just using different mediums. Craft can convey meaning just the same as art. I fall into craft as I choose clay and textiles as my mediums. This means I possess great technical skills and earn a lot less from the work I produce.
There is an element of 'craft' that is purely decorative, again it requires skill but lacks meaning. There are imposters in all fields, it just seems that this type of craft has overshadowed the true craft movement.
Or maybe it's a case of the art collectors promoting this divide, this ensures they always get a larger slice of the cake. Keeping craft as the long distant relative to art.
