Hey Gabby, The two biggies are Creative Woodworks and Crafts and Scrollsaw Magazine. Both have a variety of patterns and styles of cutting. They also have excellent articles on everything from wood types to technical information and in the back of both of them are the web addresses to the featured artists in that particular issue. Also, The Winfield Collection has a pattern club. For about $13.00 you get a collection of patterns about every 6 weeks. Some are very basic and some are more involved. They usually have several around the current holiday in any given set.
Scrollsaw has quite a few free downloads of patterns that have appeared in their magazine. It is the more expensive of the two magazines and you only get 4 issues plus a holiday issue each year. (last year they put out two holiday issues.) I almost always find something I want to cut out of each magazine.
