Crafts Sites. For a broader category, craft sites are the next best places to find templates. This is broad in a sense that they have listed sites for different types of arts and crafts like beadworks, candle making, and ceramics. Not all these do_it_yourself sites can literally hand out free templates, but will give you enough inspiration and idea to creating one. But it is best to browse on categories like drawing, gifts, paper crafts, patterns, or rubber stamping. Scrapbooking is also under this category.
Group Sites or Social Network Sites. There are usually dedicated sites for different groups depending on what they are doing. Social Networks are much broader, but groups within them like scrapmoms, scrapsisters, and so many more usually share their ideas and projects. It is up to you whether you will join any group if you want to get more details and interact with the people within the group, but you will get templates in there.
