This morning I opened the little plastic bag in which I had kept all the smelling strips from my Paris trip. Quite an aroma and a nice little souvenir. I will leave them out for a few months until the scents have disappeared and then re-use some of them for perfume testing.
Which brings me to the question? What do you use for smelling strips? Do you make your own from cardboard, go the recycling route, or do you nick them from the shops?
