I have tried Project Life and I love it! I don't fill my albums with PL pages week by week, but I do a mix. Some pages are by the week, but a page could also look like this:
Photos are taken at different occasions and the page is more of a "me and Kajsa" page, rather than a weekly page. More a theme - me and my sweet girl - but still everyday life.
If you want to see detail photos - please check out my post in the Hobbyworld blog.
