Write about a knitter whose work (whether because of project choice, photography, styling, scale of projects, stash, etc) you enjoy. If they have an enjoyable blog, you might find it a good opportunity to send a smile their way.
This is another tough question. I read a couple dozen blogs, not all devoted to knitting alone, and enjoy them. In fact, many do knitting, quilting, sewing, and other crafts. And there are quite a few designers whose styles/projects speak to me. But for this question, I'm going with TECHknitter, author of the TECHknitting blog. I've found so many useful techniques there. And I'm a TECHnique-aholic.
