As far as tagging goes it depends on they type of craft and how I want to keep track of it. I have a stack for scrapbooking, one for printables on the web, and one for other crafts like quilting and sewing. For my cross stitch stuff it is all in one notebook and tagged by category like Americana, angels, flowers, christmas, etc. In my scrapbooking stack I have notebooks for page ideas, project life, quotes, and sketches. The page ideas and sketches are tagged by the number of photos in the layouts. There is no right or wrong way to go about using evernote. You just have to do what works for you.
