Anyway, another word of advise... please know whehter your pup is f spaced or not. Otherwise the poles will not align to the holes in the bobbin and its useless.
F spaced pups are 2 inches from 1st pole to 6th pole, measured from the middle of the pole.
DivaD, this is actually a good thing to do... people will be interested, but I think you have to do a test run with a select few people. I am not really impressed by the bobbins as its pretty fragile but thats only my view.
