make
In this version you put the fists together and use a twisting movement. Do the movement twice. The hands "stay" in contact with each other. This sign is different from "coffee." In the sign for "coffee" the top hand does a rotational movement as if turning the crank of an (old fashioned/antique) coffee grinder--thus only one hand moves. But for the sign "make" BOTH hands twist as if screwing something together.
Another version of MAKE:
In this version, the hands come apart.
MAKE as in "force"
The sign for MAKE-OUT (as in "necking")
