Why do you think these things show up more than once?
I think these things show up more then once because many artists use the same materials, even if they are used in different ways. All artists need the medium they are using, something to put the medium on, and a room to work in. All of the spaces are extremely different, varying from huge studios to small side rooms.
How do artists develop spaces and methods for making their most authentic work as part of a daily artistic practice?
I think that artists spaces reflect directly from the art they are making. The mood of the room and the surroundings within the room can immediately effect how the piece is going to turn out. The mediums they use can stain the room, in a good way. These stains are the ghosts of old pieces of art, and it will always remind the artist of what they have created.
