Agreed. I've made a couple and in my limited experience I can say that you need to use at least that much, possibly more for bigger kids where you need to cut longer strips to get the length that you need.
Also, it's hard to tell but I think the shape of the mannequin/form in the pic that you posted really enhances the fullness.
