Here’s a very interesting idea: a series of perfume oil blends based on Dungeons and Dragons. The Black Phoenix Alchemy Lab has created a unique scent for each of the canonical races, classes, and alignments from D&D. Pick the three that represent your character for a completely unique scent for each character.
This strikes me as potentially useful for fiction writing as well. Smell is a powerful sense and can evoke place and emotion very strongly. Perhaps you could use scents like those from the Black Phoenix Alchemy lab to help you get into a character’s head or help sink you into your fictional world so you can get into the writing Zone.
Personally, I have a very poor sense of smell. Often my wife will comment on a scent or ask me to smell something, and I just have to shrug my shoulders. If I do manage to catch the scent somehow, I usually have to ask her to identify it for me. So for me, smell is something I don’t think much about, because it so seldom intrudes into my daily experience. And so I have a hard time remembering to use smell as detail when I’m writing.
What about you? How sensitive is your sense of smell? When was the last time you read, or wrote, a great description that included scent?
