Hey you should read some of my stories, almost all of them include a character being gagged and wrapped in a sack. Exciting!
I would find where you live, wait until you come out and then grab you (I'm actually quite small, but let's just assume I will overpower you

), hold your hands behind your back and bind them with a pair of real handcuffs. I'll tie rope around your torso and legs, making sure you can't move, gag you with a bandana and several rounds of duct tape to prevent you from screaming for help. Then I'll take you away in a black van, one which I will rent specifically for this purpose. Once in my car, I will take you by surprise and cover you headfirst with a black satin sack. I will give you a few seconds to try to escape, watch you struggle, before I tie it off tightly around your legs.
Once captured, I think I'd like to take you to an abandoned forest, tie you to a tree and tickle you mercilessly. Then I might make a fire and hug/snuggle with you, of course while you're still wrapped in the sack like a present.

Sorry I can't talk now, I'm a little tied up at the moment.
