I did my first PL this year, and have stayed with it! I used a Doodlebug album that I won, and then used the divided page protectors that I found on sale. I use whatever paper/embellishments I want to - usually a 6x6 pad or a collection for my weekly layouts. I love it!
Here's a link to my blog showing how I started ... HERE You can click the "Project Life" tag on the bottom and it will pull up each post through the year if you want to see how I've gone through the year.
I really have enjoyed doing this kind of scrapbooking this year!
