I am making a new trick & need someone to try it out. Would you like to? I will send you the instructions, all you need are two playing cards (one will be cut). Well, two cards the size of playing cards (with different back & face) will do fine.
When you’ve tried it, I’ll call you & see how it went-where I need to make changes/improvements.
Payment? I will send you one of the finished products.
I would like it if you would like to do this – first to volunteer gets the job!
