Question on hand-cranks. I have several old machines, like a 66-15 and

changed to a hand-crank. I think. Does anyone use a handcrank? How do
you manage with only one hand to handle the fabric?

My boys do it as team work! One turns the handle and the other steers
the material. It works ..... mostly. They successfully made a ragged
denim quilt for their dad with it.
