From time to time, someone reaches me about a particular online tool/ resource. I am glad that Canva reached me since I already like and recommend it regularly. It is at least a good tool for beginners and amateurs on design tools. For those who haven’t heard it yet:
Canva makes graphic design amazingly simple for everyone, by bringing together a drag-and-drop design tool with a library of more than 1 million stock photographs, graphic elements and fonts.
