I'm feeling sarcastic today (insomnia 3 days in a row will do that to me)....the answer that first came to mind was "wool". LOL! Because really "all ya need is wool" (sing to the tune of "All You Need is Love"
If you want to needle felt it's nice to have a piece of foam (like chair pad foam) so you have a work surface that won't mind being poked.
My favorite books are
Making Fairy-tale Wool Animals
Making Fairy-tale Wool Puppets
followed by
Magic Wool
More Magic Wool
http://www.thesilverpenny.com has the fairy tale books...maybe the others too.
http://www.achildsdream.com has a good selection of felting books. I would assume
http://www.mielkesfarm.com does too. They have DREAMY wool.
