I've made 35 more blankets for shelter animals! I learned about the Snuggle project via this post: http://www.craftster.org/forum/index.php?topic=212419.10
a couple years ago and just did my second batch of blankets to donate and I'm super excited about it! That stack has 12 small Snuggles, 15 medium Snuggles, and 8 large Snuggles. I have 4 more large ones cut that I want to make a simple binding for since they're cut from a Goodwill Outlet sleeping bag.
The economic downturn has lead to an increase in homeless pets. It's been shown that animals on cozy blankets are more likely to be adopted. This means more animals becoming pets in their forever homes AND if more animals are adopted shelters can help more homeless pets!
I used blankets, pillow shams and a wide polar fleece scarf from the Goodwill Outlet (where you buy things by-the-pound) and fabric remnants from my aunt's stash (mostly upholstery-weight wovens, but some cotton prints, too).
For large sized Snuggles, I used a fleece-y blanket backed with flannel and this woven cotton crib blanket (cut in half) backed with upholstery fabric.
I forced myself to simplify my process so I could work faster and make more. Any fabric that might fray a bit was cut with pinking shears and then just sewn backsides together instead of sewing them right sides together and turning. The exceptions were the 2 made from the woven cotton crib blanket since it would definitely not hold up to washing; they were sewn right sides together and then turned. I also just used black thread on all of them to save time and money.

They have a project sheet pdf file here: http://www.snugglesproject.org/docs/SP_projectsheet.pdf
Lots of types of animal shelters are signed up with their program, including specialized animal rescue shelters for ferrets, hedgehogs, etc. If you don't have a local shelter, you can send your contributions to the organization. They also accept some supplies donations. Last time I delivered to my local county shelter, they were glad to have them, but it didn't really matter than I had made them for the Snuggle Project which makes me think that animal shelters are probably glad to receive them even if they're not a part of this particular program.
Lastly, while working on these I posted about it on my Facebook page and at least a couple of my friends showed an interest in helping. If you craft for charitable causes and participate in social networking, post about it to spread the word!
