Go to ebay and search for wool roving. Spinners (the kind that make yarn, not use powerbait) use this. Its really, really cheap.
I just bought four ounces of angora. I use wool carding combs to mix in Angelina fibre for sparkle [url=http://www.texturatrading.com/angelina.html.:a702a]http://www.texturatrading.com/angelina.html.[/url:a702a] Awesome dubbing. Pick your colors.
Try finding a wool and fibre fair in your area. I have one here in Maryland in May [url=http://www.wggb.org/sheep.htm:a702a]http://www.wggb.org/sheep.htm[/url:a702a] This will open your eyes big time. What you spend for one little quarter ounce of dubbing can buy you 10 times this amount at a wool fair.
Enjoy
