so what would be an easy method for winding a pankace coil?

seems like it would be difficult to keep it from popping up on itself. could it be glued down onto a piece of cardboard or plastic sheeting? that would be a mess if it wasnt wound the way you wanted or if the coil needed alterations.

perhaps a dowel in the center and two pieces of cardboard close together, and would inbetween the two pieces of cardboard? that would take a long time though.
