If you go to the
shop and check out "templates", on the left column and click on a designer to see what templates they have - there are so many really good ones to choose from.
If I were you, I'd check our
365 Project Gallery gallery first to see the incredible pages done by dd members. This way you can first decide if you want to do daily, weekly, monthly etc., and get the templates to match. For a first try, you can look in the freebie section - link is on the top row of this page. You're never too late to start this project - there are no rules except to have fun!
