Simple things are best.
I love the smell of ink, paint, concrete, and sawdust.
Working on projects that smell good during the making is a nice way to spend the day.
Prints, paintings, architecture, and wooden boats have satisfied that need over the years.
Oddly, a black Pentel Rolling Writer on a bar napkin is the starting point for almost everything.
Art Gym has every smell I'm looking for, and there are napkins in the coffee shop...
