Help How to perform long/measured drop suspension properly?

[needtodiequik]

First of all , hello everyone. This is my first thread I post here. I want to gather enough information to perform painless long/measured drop suspension method.
I did my research on internet but I still have plenty questions to ask. So let's begin with first question

1. Is 16 mm (0.6 inch) thickness of rope enough or do you recommend thicker one?
2. Which knot should I use ?
3. How to place rope on neck ?
4. Should I put something between rope and neck to reduce pain ?

That's all for now.
As I said I want to ensure information before perform this method. So thanks by now ;)

Hello. If you look in the sticky thread called "list of resources", near the top of this forum, you'll find a lot of useful links. The one called "how to hang yourself" is more about partial suspension, but it covers ligatures, knots and so on.

I hope that helps. And I'm sorry about whatever has led you to contemplate this.
