Epoxy glue and epoxy putty are essential materials for making armatures and build-up puppets
So with both these materials, you don't need to measure how much you dispense of each. Just eyeball it and mix them up, then apply to your project. (So, for the glue, get a scrap piece of wood or paper, squeeze out a dime to quarter size drop of each, mix with a toothpick and apply)
