Why place a fabric softener sheet in your luggage when packing? It will absorb odors and keep clothing smelling fresh. Great for freshening up sneakers also.
I had a leftover fabric softener sheet in my suitcase after a trip where I did laundry in my hotel. Instead of throwing the fabric sheet away or taking it back home, I placed it amongst my clothes in my suitcase. Everything had a nice clean scent to it. Now I always toss a fabric softener sheet in my luggage.
Another benefit: if static cling is an issue with a skirt or slacks, just dampen the fabric sheet and rub it over your pantyhose. Goodbye static cling!
