Here's the perfect, collapsible, packable fower receptacle.  Made of vinyl and suitably embellished with a variety of attractive "decorator" fluorishes, it can be packed flat in your suitcase.  Stop at a flower stand on the side of the road on your way to your host's home, whip out your collapsible vase, stuff in some posies, and you're ready to be the "perfect stranger."  Fill with water at your destination and it stands tall and eminently giveable as a hostess gift...or to make your hotel room more Shabbos-dic.
