Heh, I've learned that lesson, both ways. I am in love with PotL but can't wear it around my sister, lest her dramatic gagging sound effects put me off. I also personally dislike Angel a LOT and it seems very well liked by many people.
I don't blend my own perfume but the only way I scent my house is an essential oil burner and the best quality oils I've found come from a company called Aroma Vera. They used to have a bricks and mortar location in the town where I grew up but as of now I use their website. They can seem pricey compared to other places but as far as essential oil goes I think the quality is worth the price. My most-used oils are lavender, Roman chamomile, neroli and clary sage, and combos thereof.
