In the past it was art that developed the craft. Now that there are so many crafts around, art is no longer the driving force behind developing crafts, and has since taken a huge change.

What is a craft? How can we explain it?

It appears that a craft is the way and method of using a medium of expression that all artists and craftsmen have to master. There is no restriction of medium/media. Hence, the lowly craftsmen, is essentially inside every artist.

Art hasn't gone downhill, its the artists who had done so.
