How can I get curls to last with my thick, nearly shoulder length hair? What's the best way to curl it?

So I have thick almost on my shoulders red hair. My hair has never done well with lasting curl. I had a short bob hairstyle but am growing it back out. It's at the point where I can't flat iron it smooth, but would rather curl it with big loose curls. Please help :) Thanks!How can I get curls to last with my thick, nearly shoulder length hair?

use a flat iron and roll it up to the top of your hair. if you twist it a certain way the curls will come out looking really cute.
