There's the all out simple approach - zener cards with a partner (circle star square waves plus). Get more complicated with colors and shapes. Or fruits. Whatever. As for technique, I visualize thoughts flowing into the person for transmitting and the opposite for recieveing.
i havent tried this myself but it sounds serious to me.

Okay I'm just gonna be short and to the point here.
Write any way you can practice telepathy here. A lot of sites talk about it, but give no practical exercises for well...practice. Just do this and that and you'll do it, right? Wrong. I'm prepared to get a partner, just list some please!
