I haven't tatted since I was a child and an elderly aunt supervised me. I found the following websites with free patterns to check out:

http://www.craftown.com/tat.htm
http://www.bellaonline.com/subjects/3737.asp
http://www.be-stitched.com/tattingpatterns.asp

and there are probably some good tatting books on Amazon.
Ooh! I see you do needle tatting. What I was taught was shuttle tatting. Some of the websites I posted say the patterns are adaptable to needle tatting. Found these websites that are specific to needle tatting:
