Faux silk scarves, at least 3 (a blindfold is a must!) and you can get those at any walmart or target. Target also sells soft rope, 50ft length, for about $12, but rope is tricky-too tight will hurt(even soft rope) and too loose will slip and slide.
No bedpost? Tie the wrists behind the back before lying down. I prefer legs not tied-makes the ride a bit wilder
The local Halloween store here sells wrist and ankle shackles for about $8 each-they're a thin leather and the chain between them isn't for roughness, but they'd probably do just fine.
Have fun!!!
