Embellish with plants, fruits, and booze.
Price range: $5 - $40 (depending on your liquor preferences)
A healthy plant says, "I know how to take care of something other than myself!" And fruits add a bit of elegance to an end table. There's a reason all those Renaissance artists spent so much time painting pears and stuff, you know.
And last but not least, expensive alcohol is a surefire interior winner. Deck out the shelves of your TV units with half-empty bottles (or full, even better) of scotch or whiskey so you can drink while you decorate. Cheers!
