Machines Fixed

Well the machines are both now sewing perfectly fine. The problems? My thread seams to have been the trouble as as soon as he put in his threads and changed a needle (although I had done that already), both sewed fine ! Grrrr so two hours driving and five minutes in the workshop! Needless to say I have invested in a few boxes of their threads and will not use the cheap stuff on my machines anymore. (Until its my last resort because I need the colour for an urgent repair or something! )
