I use my amenity bags to clutter up my bathroom cabinet until I get fed up and turf 'em.
I do use two QF first class amenity bags to good affect however, AND for what they were designed for:
* that brown one with three compartments that you can hang up; it is lightweight and terrific for holding my set of travel toiletries
* a George Jensen amenity bag; surprisingly good quality, and I keep it at my gym to hold all my toiletries
