Maybe some of you have already stumbled on these (I'm still finding my way around the digi sites), but here's some blogs I've recently bookmarked.
http://scraporchard.com/ (register for their forum to access all the entries to their new contest -- they're all downloadable! I'm currently downloading from there! LOL)
http://butterflyhollowdesigns.blogspot.com/ (quite a few LARGE size kits for free)
http://vicki20.blogspot.com/ (she adds pieces to kits every few days. All of her freebies are archived and can be accessed anytime)
http://www.mywalkinglife.net/scrapblog/?cat=8 (lots of nature themed kits, she's not posting anything new but the older kits can still be downloaded)
http://lalalime.blogspot.com/ (she put out an awesome set of zoo animals -- very realistic!)
http://audraslittlescraps.blogspot.com/ (more cutesie type of kits, some religious themed)
And of course http://digifree.blogspot.com/
Anybody else got any new discoveries??
