How do I make .1N solution of NaOH?

Boss needs me to do this. Chemistry isn’t my strong point but he doesn’t know that.

I don’t need a lot, just a small amount. So like 1mL. He wants me to make a .1N solution of 1.5M NaOH. I was trying to find in the lab what I could start with and found some 6N NaOH. I’ve never dealt with Normality before so I’m not sure how to treat this. Do I just dilute the 6N NaOH to make it .1N? What do I dilute it with? But wait – how do I make sure it’s 1.5M? It doesn’t read on there the Molarity, so should I just start from scratch with some raw material?
