Is it possible to knead MMF too much? I can see where it would be a problem if you don't knead it enough, but can I OVER do it?
I think it will dry out maybe. Good question.
I agree - the only problem I see would be to have it out too long and dry out on you. I knead mine over and over after I begin using it - use the scraps - knead again - never had an issue.
