Wayne Fox from nothing hidden was very kind to create a tutorial series on WireframeSketcher. In 40+ videos he goes through everything from basics to how to wireframe an entire website.

For your convenience we’ve created a YouTube playlist where you can find and watch all videos in this series. Note that the first 8 videos are using long format and show how to build a complete website. The rest of the videos use short format so you can watch them quickly to learn a new feature.
