When we were down at Glenn's we all went to a Civil War thing - There was a lady there with a machine that had a knob on it. The knob was fixed so she put a fabric cover over it and it turned just fine.
AH I have a picture - You can see the little blue cover she made for the knob. The knob doesn't turn at all it is just a knob. The little blue cover turns - even a thumb cut off a mitten would work...
