Oh, this is a great idea!
Here's a picture of just my normal haircut. Please excuse the no smile, I took these for my sister-in-law to give to her hairdresser to cut her hair similar.
Here's some of when I've fixed it up. I usually do either 20s or 30s depending on what's going on. Most of my 30s ones, I have hats on though.
this one, my mom did some fingerwaves at the top and then I used sponge rollers around the back.
This is when I used the those pink plastic waver things- I can't remember what they're called and small hot rollers
