Have found a great free site http://www.freepatterns.com/. Loads of free craft patterns for you to use or to learn new techniques. I found it because I was looking for instructions for Polish Star Stitch and have found loads of other great new stitch ideas too!
Another free pattern site I love is - Knitting Pattern Central there's also a link from there to a similar site for crochet
And if you're into "antique" crafting, there's a fantastic directory of patterns from the turn of the century - The Antique Pattern Library - knitting, crochet, cross stitch, embroidery, lace making, tatting and much more.
I made a lovely dress for my daughter out of a £2 remnant of black fabric, and as I'm not the world's best dress maker I thought I'd crochet the top. So we went into the antique pattern library and found a beautiful pattern for some 1920's lingerie, which had a top made of crochet flowers joined together. We then adapted the pattern and used double knit yarn to make the shoulders and neck line of the dress. Photo's will follow!
