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.
Scrapbooking Sites and Blogs. There are a lot of scrapbooking sites out there and bloggers that will offer you free templates. This business is very competitive that even hobbyists are willing to give out their ideas for free. These are the best places to look for templates because you will also get ideas from their previous projects, and that they target specifically for scrapbooking. These sites offer tips and articles on how to put your scrapbook page together, just in case you have a difficulty in making a scrapbook.
