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.
This approach tends to work better for articles that are jam packed with information and/or those that take a broad, aerial view of the topic, but it can also work with articles that are a close up view of one specific topic. For example, I've written many articles on how to create an effective resource box, and from that one very laser beamed topic I have branched off articles on extremely specific elements of that already specific topic. I assure you, no matter what your article is about, you can write about it more in depth in a new article.
