If so, care to help someone who knows next-to-nothing about the craft get started? IRL I rescue domestic rats - lab, pet, commercial, you name it. Live with a bunch of them in my house and probably know their anatomy and habits better than I do about humans. The one characteristic shared by "Halloween" rats is their hilariously inaccurate anatomy. I love 'em for what they are, but this year I need realistic ones. I've seen some needle-felted rats on Etsy that are absolutely stellar and although I could buy them, where's the fun in that?

Links to tutorials, web sites, books, etc. greatly appreciated!
