|Luigi Russolo, "Profumo", year 1910|
We are used to smelling paper strips for convenience, reliability, and practical purposes.
Unfortunately, paper is NOT the best material to smell. There is something better. It's the heavy, complex, "winter-season" fabric. Your heavy coat, for example. Or a "furry" synthetic coat.
Why? for a simple reason: complexity in structure. It's not "flat", but almost three-dimensional.
Fabric is not flat as paper is, but it's thick and with complicate structure. When you spray perfumes all over fabric, a bigger amount of perfume will be trapped. Perfume molecules will adhere on every point of the fabric 3D surface.
