Go get a large perm rod, you can get them in a hairdressing supply shop, or a large chemist.
For the mane, either roll one rod in line (parallel) with the plug line. Or for more spiral curls, use three rods vertical ( like how you'd do straw curls). I find it easier to roll the hair with perm papers, or tissues work well too.
Have the hair damp before you start it'll be easier. Then do the boil perm when you've finished rolling. If you blot excess water off after the boil, it will only take a few days to dry.
