My little house?:
Sometimes musty. It's old (over 100 years worth) & I'm not exactly the dusting/vaccuming queen!
Sometimes (like this morning) just wonderful!
Every door & window open to let in the fresh air before a scorching hot day.
Other times I love the smell of almost any Japanese incense. My current favourite is Morning Star rose! Heavenly! Aaaaaaaah!
Other times, Nag Champa (agarbatti). A no-nonsense (but heavenly) incense, courtesy of Sai Baba. (& no, I'm not a follower. I just like the fragrance!)
