Furniture: Doesn't have to be yours, doesn't have to be fancy, could be found at a fancy location or the city dump because furniture is furniture regardless of condition.

Life: Broad range of interpretations available here.

Weather: Another fairly broad range subject. Could be icicles on a water fountain, snow dusting the trees, a crowd of umbrellas or any number of things.

Process: not feeling this subject personally.

Necessity: Things that are needed, the effects of the wind could show air, rain could show water, a group of friends to show companionship etc.

Groceries: Kind of bland but could be fun.

Work Space: Any area that some form of work takes place from gluing models to making billion dollar deals, it's the space a person works in, not always your own.
