Link to lined pages http://www.incompetech.com/graphpaper/. Variety of styles and types (PDFs), which can be customized and printed for practice or whatever.
Here is a link to PDF that prints Seyes, or "French Ruled" paper. I found it on FPN.
Seyes paper is apparently used to teach handwriting in France. Here's a link to A video produced by Brian Goulet, explaining how to use it.
