Hi group:
How does the Ekich bobbin work to take up thread? Say I have 10 inches of thread out, do I tug on the bobbin and the spring tension takes up the slack as I slide the bobbin back toward the hook? What determins the strength of the spring tension? What makes this bobbin better and faster?
I checked their sponsor site and sent them this thread rewind question also.
Thanks to all:
Bob Scheidt
