add some flash to your bar by picking up inexpensive decanters and carafes at thrift stores.
Personally, I've never been able to have more than one bottle of liquer, one bottle of vodka and a case of cellared wine at any given time. I asked a friend how he manages to keep his liquor cabinet stocked - his reply, 'Have guests over a lot. They always bring a bottle or two.'. Thanks Kev.
A simple home bar can have:
sweet and dry vermouth
a few liquers
soda (ginger ale, cola)
fruit juices (oj, cranberry, grapefruit, Clamato)
