Know the ropes :)

Since it's a bit quiet around here; let's spice things up, shall we? ;P

First of: I am certainly no pro at bondage. I am here to learn! I know a few knots. And I used to have some lovely rope that a former lover gave to me. Didn't cut nor leave marks. Lend it to a friend a while back, but it was never returned :( Sadly I have no idea what it was made of... I am ready for some more experimenting with my new boyfriend <3

So, for all you kinky lovers out there: what's your favourite type of rope? And why?

Also: what's your favourite knot?

Links and instructional video's are also appreciated :)
