I would get more than you think you need, just to be safe. You can always use the extras to make other accessories like cuddle buddies and hay holders, etc. Plus now is a great time to buy because a lot of fabric stores have sales on blizzard and anti pill fleece since it's warm. I picked up some from Joann fabrics the other day, and I was able to get some awesome patterns for 4.99 a yard, instead of the usual 10 bucks a yard. The same sales are also online if you prefer to order it there.
