Rope bondage ideas, advice?

My wife and myself are in to rope bondage, to be honest the only thing we have really done is breast rope bondage, we normally tie her breast up in some form of rope bra, usually as tight as we can get it as she likes how hard and sensitive her breasts feel and I like how blue/purple they turn, she has quite large breasts and we have various ways we have tied them up, my favourate being laying the rope so that it forms a sort of tube to make her breast stand hard and proud. looks great.

Has anyone got any other techniques or ideas please that we could try, the more extreme the better as we're very adventurous but no neck bondage as thats a big no!

Cheers all
