I use separate paper strips if I feel like it. I cut a long wide strip, fold it in the middle and then cut pieces of appropriate width as needed. Generally, the laminated formers width provides enough area to attach most of the skin pieces to. For some extra area, sand the edges of the former down a bit and glue strips to its circumference, like here:

By the way, the most tricky part of the model is the nose (F18-F20). If you do well on the nose, the rest will be easy.
