The first place to look (besides the sites listed on the right hand side of the page) is Facebook. Almost all designers and companies have a Facebook page where they offer exclusive materials that can be downloaded as "outside content." MyMemories even offers a Friday Freebie that can often be downloaded directly into your Software Suite Volume 3! I found that the best way to find new designers is to go to a page (like MyMemories) and simply "like" all of the companies and designers that they "like." NOTE: You MUST like a page before downloading exclusive content. Very quickly you will see how much content is to be had for free with only the click of the mouse.
Occasionally, design companies will host a blog/page hop. This is a communal project among all of the designers the company uses and almost always coordinates in colors. For Black Friday (available this week until Sunday), Scrapbook-Bytes is hosting a Facebook page hop which has absolutely nothing to do with shopping!!! The colors are vibrant and varied, but they look gorgeous together. I downloaded approximately 10 zipped freebies which even includes several alphabets! This is the perfect opportunity for developing your outside content folders. The only limits are the boundaries of your imagination. This is one I created using an old photo of my pet, Cleo, and the Black Friday Facebook Hop downloads. I wish you all a very happy Thanksgiving with tons of memories to scrap!
