well a lunge line and a log or something to get her over would be helpful
but as long as she leads use a lead line and get her to jump a log, or a fallen post or something you can get her over.
We had a mini at my old barn that would jump in hand over almost anything you put in front of her, took her some urging the first few times but she got the hang of it.
Just be careful, jumping can bring out a whole new side of your horse, be prepared for a buck here and there from her, don't punish her for it unless she does it EVERYTIME, jumping may just feel good to her.
My TB will throw a buck on the trail after a jump =]
