I am sorry if this has already been done, in fact I remember seeing a tutorial on this at one point but I can't find it. So if anyone knows of a tutorial to make a werewolf rug please let me know!
That is a really good idea. I could probably sculpt the claws for the paws as well.If you can find a werewolf mask you can foam fill it . either with ab foam, or VERY carefully and slowly with great stuff. I think Stillbeast has a youtube tut for foam filling a mask with gorilla glue too.
Cut out a wolf skin shape from a large piece of fake fur (most of the fabric stores have coupons on their websites, could make a big difference on price for something like this) and sew or glue them together.
I am working on a "taxidermy" werewolf head using this method right now.
