Well, art is in the eye of the beholder. So to some eyes crafting fine scale models
is art, to others it's playing with kid's toys.
So, maybe art is the perception of things the viewer feels he cannot do. The more capable someone is at something, the less magical the end result is. So to some a virtuoso violinist is wonderful, to another violinist it's merely sawing at strings.
I remember watching a plasterer, that's right, somebody who coats walls with plaster, and I was amazed at their ability. The fluidity of motion, the sparse expense of effort, the silky smoothness left by the stroke of the trowel (not to be confused with trowl. arf! arf!). I have tried to plaster, and it has not been pretty. Is the application of plaster an art? Not really, but it can appear to be artistic.
Nevertheless, Trowlfazz is correct. Without putting pressure on ourselves, it's a great outlet and craft and lost of fun!
