The second trick is to layer your design. An extra layer gives the display more dimension and depth. Store displays always use the layering technique. Layering finishes the display---you don't wonder if there should be something more. But, beware not to add so many layers that the display appears too busy. You need to know just when to stop.
Since a picture is worth a thousand words, let me show you how to incorporate these techniques:
on it's own.
Adding another layer with the candle light and stars
makes the display look finished,
and now it really "pops" (4th of July pun).
The large letters and flags look great. . .
but with the addition of stars and vine balls,
the display appears more finished.
The stars repeat the colors in the flags and
the vine balls repeat the black in the letters and candles.
And everyone knows that good design repeats itself.
Okay, the design philosophy lesson has concluded.
Now, your homework is to go try these tricks
in your home.
