When it comes to the text and the font I use, it is very important. As different fonts can give off different messages. I was looking around trying to find infographic font packs or font palettes, much like for the colour palette for Flat UI Design. When I came across this website, http://designschool.canva.com/blog/tips-for-pairing-fonts-in-your-designs/, this website give tips for pairing fonts in your designs for infographics posters and in general for any type of design work.
Here are some screen shots of the website.
I will be using this website to help me decide what fonts and what combination of fonts to go with. I will then use them in my next post which will be the initial development of my poster on Adobe Illustrator.
