I have just started a blog on favourite tutorials I find called Craft Digest - http://craft-digest.blogspot.com if you have a favourite tutorial you would like to share or have one from your own blog I will add it and link back.
I have a page on my blog where I place links to tutorials I may want to find again, and which I may want to refer others too. You may find some there you can add to your blog as well.

I've quite few tutorials over at http://deepashome.blogspot.com/ . The links are on the sidebar. There's also a compilation of basic outlining stitches and filling techniques in hand embroidery.
