LOL amma, it's like when the petrol in the car is running low and you speed up to get to the petrol station faster! :lol: Only that uses MORE petrol, at least bobbin thread is consistent. :shock: I'm ALWAYS over estimating how far it will go. You take out a half filled bobbin in and look at it. IS it enough? Yeah, it'll do! Of course it's ALWAYS about 3" too little. I think they call this 'the triumph of hope over experience', or maybe just 'you stupid idiot, Kathryn, when will you LEARN'! :lol:
