i watched this as an idea
but i ultimately ended up wrapping the hair around a bottle (small non aerosol hairspray bottle) and pinning it inside the rolls after carefully sliding the bottle out.
for the bangs i did the same thing (i dont have bangs) and then pinned them underneath.
you can either use a curling iron on the bottom or wrap it in a bun till it dries and then it will be mostly straight with a wave to it
here is also a clip for great pin-up/40s style make up
if you have any questions i can try to make a video for you! feel free to also pm me
