I was wrong on all counts!
Here is my hair in a 1930s style WITHOUT the middy:
The curls bounce into place and stay put. They might even be done with hot sticks, too. The curls and the hairdo stayed put all day.
Here it is today WITH the middy cut:
Absolutely terrible. This is pincurls that I slept on. They just brushed out into FEATHERS. This happens no matter wet or hot set. I simply do not have enough hair to create full, bouncy curls.
Maybe the hair cutter thinned it out too much -- I don't know. But the "middy" just isn't working for me -- unless I change my style to Leather Tuscadero :/
