The sign for "make" has a couple of popular versions.
In one version you put the fists one on top of the other and use a twisting
movement. Do the movement twice. The hands "stay" in contact with each
other.
Note: The sign "MAKE" is different from the sign "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.
There is another version of the sign for "make."
In this version, the hands come apart.
