I have already shared some of my favorite (free) digital scrapbooking sites, such as:
House of 3
Free Digital Scrapbooking
Here's another great one to add to the list:
Raspberry Road Designs
They offer a lot of "Quick Pages" (QP), which I personally am not too interested in, but they also have some great free alphabet sets, paper packs, and element kits available to download.
And of course, I still recommend the awesome (and free!) GIMP to put it all together.
