I never tie anyone else up, so for me there's no mood to set.
As for the mood that was set for me by others, my cousins used to use different variations of xtc's method - heck, I think they even used a pillowcase on me themselves once. I definitely remember a canvas sack on a different occasion when we were out at a neighbor kid's barn. Usually though, they'd either come into my room with rope in hand and announce I was about to get tied up (allowing me to lay down or sit up as they instructed), or simply ambush me from behind if I was somewhere else and wrestle me down. Ambushing me as I emerged from the bathroom was a definite favorite of theirs; they must have done that one at least a dozen times or so during the time I lived in their house. It always worked because I never
seemed to notice them; actually, I usually did after the firest couiple of times because of my over-sensitive ears warning me ahead of time that they were there but I pretended otherwise to let them carry on anyway!

Dare to be different... and make a difference.
To boldly go where no one in their right mind has gone before...
