If you are talking about handwriting, I have found some great sites where you can print sheets including blank lined sheets.
The way DD's school introduces it is a lot of time following the zig-zag lines and then building from there. Another option is finding wipe off books with mazes and allow him to do them repeatedly and his control will come in no time. Of course, I am making assumptions that he doesn't control at this point and he might be miles ahead of this process. If he is than I suggest printing out the letter samples. We did the letters of DD's name which excited her, but some people just start with the beginning of the alphabet and go from there.
The site I have bookmarked and use regularly is
http://www.handwritingforkids.com/, but there are many out there.
