Some enthusiasts go out and buy a lot of scrapbooking templates, and that's really fine. But sometimes, you don't feel like going out, or you don't want to spend a little more money for your hobby. That doesn't mean that you should stop scrapbooking, though. You can always go online for your scrapbooking templates, and there are a lot of websites offering beautiful templates for free, so you don't have to pull out your wallet or credit card. All you have to do is download and print them, and you're all set.
Theme Sites. These are of course thematic, which will be helpful on what theme you want to use in a page. Scrapbooking is like Wordpress. If you are making a website powered by Wordpress, you will look for nice themes that you can work on instead creating your own. It should be appropriate in the long run as you post and update it. In scrapbooking, templates will stick for a long time after some time of adding all the elements, and it will be the basis of the overall look that you can't change. Photo Sharing Sites. These sites are both theme and group sites at the same time. Photo sharing is mostly their goal, but I have seen scrappers post their layouts or projects. So you will get templates or their ideas as well.
