Diagonal Crochet    
    I haven't actually tried this yet,
but here are some of the links I've collected, just in case.
Not all these patterns use the same stitch. 
Usually when people look for the diagonal stitch,
I think they're looking for the diagonal box stitch

Many of the above patterns are from web-sites that are no longer on the web.
Although the archive site tries to get as many of the disappearing sites as possible,
many just disappear.
It just shows you that if you see something you like, you better print it out or download it at the time,
because, next time you look, it could be gone.
And even if it's on the archive site, you do need the URL to search for it.
