Help with hanging

[Phoenix]

I'm considering the hanging method seeing as every other method is unattainable for me.
I've read people pad the noose as the rope can become very uncomfortable around the neck - how would I do this?
im around 5'4 and weigh maybe 15 stone so I'm fairly heavy - what type of rope would I need? Are they fairly easy to get in a shop? I couldn't get anything delivered due to not living alone and raising suspicion

Someone could pad the rope with a wash cloth or a torn cotton shirt. Not too thick not too thin. It also helps close some gaps. Look up everything many times and take your time figuring things out.
