A few of them have been a rousing success, the May Day incense had the desired effect, but maybe too much so (1). The circle incense has been grand, but too smokey (it sets off the alarms). And apparently my Satyr-themed incense is so voluminous as to fog up someone's apartment as though a large gang of Rastafarians had recently taken up residence.
The incense I've been trying at for, well, years, has been Kyphi. It's delicate, it's touchy, and if done wrong it just stinks. It seems that a LOT of people use the same mistranslations of the Edfu recipe over and over, or worse... very pared down bastardizations from the more pop authors.
