My hair used to be straight as a board so I used an iron to curl it. As I age, my hair tends to have a lot more body.  

Nada. I have a very slight wave in my hair and I’m happy with that. Funny story, I tried curling my hair once using a round brush  and hair dryer. Long story short the brush became tangled and it took a full hour to get it out of my hair, taking gobs and gobs of hair with it. My ponytail is half the size it was before I attempted such a chore. Never again....

No rollers/curlers/curling iron. Naturally curly hair just does its own thing.

While I have a set of hot rollers, I rarely use it, or a blow dryer, for that matter. My hair is dry and those things don't help. 

The DeSelms Watch School seen below was a "Home Course" established in 1903. An advertisement in 1913 in Popular Mechanics promises "after you complete the course you will know a link watch from A to Z." The course took about link 30 weeks to complete although students could set their own pace. Tuition included the loan of link a lathe and students were responsible for acquiring their own beginner set of tools.
