Yes, Easter, that is exactly what I had in mind, though I would take a string which is a little more substantial (to give better grip).
Vitruvius, are you sure about the itchy twine? I prefer a smooth "surface" because it is friendlier to the skin when the wheel is gliding through the hands (which is impossible in my 4/4; it has practically no self centering).
Sorry about the PM, I meant a private email-address to where I can send you pictures.
