We get this one a lot. A project is a more simple and quicker way for users to share what things they're currently tinkering away on via a picture of your latest craft with a brief 2-3 sentence description. A how-to, on the other hand, involves a bit more. They have the picture and the description of a project, but how-tos also have a step-by-step guide, teaching other CraftFoxes users how to copy their craft.
