Tickling Method
The tissue method of tickling involves placing a thin layer of tissue on the skin of another person. This can be on the chest, stomach, back or around the nape of the neck, depending on where the person is most ticklish. Pinch the center of the tissue and gently drag it around the skin. The sensation should be both pleasant and ticklish at the same time. You can vary the tickling motion too by scrunching up the tissue and leaving thick creases in it surface, which will affect how it feels against the skin.
Build-Up Method
This method is designed to tease the person being tickled by building up the tension from gentle touches to full-on tickling. Ask the other person to lie on his front. Gently run your fingers along the breadth of his back and then make the some motion up and down his sides towards the armpits. The armpits and waist area should be particularly sensitive to tickling. Increase the pressure with each movement of your fingers until you are digging your fingers into his sides.
Feet Tickling
Ask the person who wants to be tickled to lie down on a bed with her feet hanging off the edge. Sit across her legs so she is slightly trapped and can't see the lower half of her body. The sensation of being trapped will add to the sense of giddiness and excitement. Roll her socks down a little so her heels are exposed. Start to tickle her heels with a feather or with your fingers. Move the socks a little farther down and move onto tickling the soles of her feet. Remove the socks suddenly at the end and tickle all over the feet.
Anticipation Method
This method is designed to increase anticipation by letting your tickling victim know what you are going to do next. For instance, if you are tickling the soles of his feet, tell him you are going to switch to his stomach soon. The sense of excitement and expectation should increase the giddiness and make the tickling more effective. Even if you trick him and go for a different spot, the anticipation will still cause the person to be more ticklish.
