Here are some useful resources that were used for creating these free powerpoint templates.
Firstly, I used lots of different fonts (many of which are standard fonts that everyone has):
• Arial Black
• Times New Roman
Other free fonts used:
• Caviar Dreams
• Century Gothic
• Clear Sans
Your downloaded powerpoint template will look better if you have these fonts installed on your computer (or just a particular font that the template uses).
In latest designs free icons from SmashingMagazine were used. Some other great resources for beautiful and free icons that you could import into your powerpoint template are IconArchive and IconFinder.
