Bondage - Do you have material or colour preferences?

It was always black leather for me but now moving towards nickel-free steel for wrist and ankle cuffs

You know me Ms Wilde, I'm a black leather kinda guy ;)

Same for me! My Oh seems to like a splash of red thrown in there too.

Our favourite colour is red or black. I prefer satin on some occasion or velcro but chains are nice too.

I prefer leather or silk in my three favourite colours. Either black, red, or purple

I would love to see day collars in sterling silver or stainless steel. Particularly like ones that would not raise suspicion in the vanilla world. Perhaps bracelets too.
I also like black leather,pvc,chains and wood. As someone else pointed out literature would be good too explaining how to play safely with certain equipment. What also is of interest to me is the mental aspect of bdsm as opposed to fsog type of fantasy literature.
