For example, most word processors contain fonts such as "WingDings" or "Dingbats" which contain symbols such as hearts, arrows, and curlicues.
Dingbats, decorative free fonts that have a small picture for each character, are especially good for this technique.
You can find a number of free dingbats on sites like Dingbat Depot, Acid Fonts, and Font Freak.
Use free dingbats with a Christmas theme to decorate the journaling block on your layout.
Use font dingbats or the shape drawing tools to create a pleasing design on a 2x2 canvas.
