The wonderful thing about fiber is that it's so versatile. You can spin it, felt it, knit with it, use it for stuffing - you name it! And there are so many different fibers! Wool, alpaca, cashmere - love them all!
I enjoy wool because of the many different things you can do with it, but as far as knitting goes, I prefer something softer like cashmere, alpaca or silk - they're a dream to work with!
