All of this has been tremendously useful…particularly getting round the problem of impossible-to-unscrew spray tops…thanks for the tip. My point here though….I am a mad decanter because I love mixing up fragrances…..one current success is with two Lush scents, Karma and the new Vanilla. I once told the local Jo Malone saleswoman that I routinely did this (Lime, Basil and Mandarin plus Grapefruit at the time) and she actually told me it was forbidden!!! Do any of you have any opinions either way…or any good recipes??
