Here is a site with many, many stitch patterns and I like it very much:
The links on the sidebar ending with "raksti" will show you the stitch patterns.
I'm sorry to say that the site in not in English - it is a Latvian site.
But I think it's not necessary to learn the Latvian language - experienced knitters will have no trouble with the most stitch patterns, they are all shown with charts.
And here is another site with many stitch patterns but it is a German site without charts
Clicking in the sidebar will show you lots of stitch patterns. I would be glad to help, if anyone is interested in a German pattern :waving:
