This was not only a fun project in its own right - who wouldn't love making zombies???? - but was also terrific because the kids weren't afraid to take some risks and try new things; after all, who the heck can tell if you mess up a zombie?
The book is available on Amazon for less than $12 and has all sorts of patterns ranging from easy to difficult; I highly recommend it.
I won't be sharing any patterns here due to copyright issues and whatnot, but I will mention that if you search for "zombie felties patterns" you'll probably find a few online.
So what are you waiting for? Go fill your classroom with zombies already!
