I'm a total pushover for anything that smells like a pine forest. Not a cardboard car freshener kind of forest, of course, but something with the authentic scent of the deep woods. Soap & Paper Factory
makes a room spray, room diffuser, soy candle and shea butter soap in a divine scent called "Roland Pine" that's so amazing, all the other scented items in our home have been currently shelved. Personally, I'm not fond of diffusers (never have been), but I use the soap with every shower and I use the spray to quell any of unfortunate canine odors. The candle sits here in my office at my desk (unlit, of course -- don't want the fire marshall coming after me). Every time I lift it to my nose, I can't help but wonder, "Man, how did they get pine down so perfectly?"
