Many thanks for your lovely reply and all the great ideas, Missbattleax, very helpful!
I actually have an Yves Rocher in walking distance and a place to check out the Miller Harris and Tom Ford scents just opposite, so will do that today or tomorrow.
Great tip re expanding one's database by smelling everything! I'll definitely try this and have already started with several plants, my coffee and the cat this morning. Normally, I'm mainly a very visual person, so really interesting to concentrate on using my nose more for a change.
Have you ever done / would you like to do one of these 'create your own perfume' workshops some brands / parfumeurs offer? I imagine it is a lot harder than one would think to create anything half decent and interesting!
One more question: I noticed you recommended an H&M fragrance upthread. I just discovered those on the website a few days ago and some get great reviews, though none of them seem to be available anywhere near me. I've currently got Makassar Patchouli, Mirabilia and Sparks will Fly in my shopping basket (very heavily reduced!), any opinion on those?
