I was at the Salvation Army store where my daughter lives in S. Illinois and saw two of the 4-cup yogurt makers for $1.40 each. Are they easy to use, and would anyone have directions, because there was none with them. When I go back, I am going to run in and pick them up if some of you would think it would be a good way to make yogurt for family and chickens . . .I know they were really the rage back in the 70's and 80's I think, then like everything else died out . . .
