Here is a simple and frugal decorating idea.
Get a punch bowl (or for that matter any decorative bowl will do).
Fill this bowl with fruits we usually have apples and oranges in ours.
It serves a dual purpose.
One it is a beautiful and easy display and
second it serves as a reminder to reach for the fruit instead of the junk.
( I am so guilty of that one.)
