You can often find it in Hancocks. It is not usually found at the front but in the back. Look in drapery and or upholstery shops also. They always seem to have a stash.
I've tried at Hancocks. They didn't have what I needed and only had two colors of fur but too short. You used to be able to find it everywhere. The sites are expensive plus they want to charge a pricey shipping fee. Thanks everyone. I'll continue to look.
http://www.crscraft.com/ has lots of fur - it is under "bear supplies" it may be of higher quality than you are looking for tho. Good luck.
