Hi again, I just want to say, thanks so much for all your help ladies -I am going to try and adjust the bobbin tomorrow. I have the manual tension down to 1 and a half-I am right in the middle of an art quilt and the stitches are OK on it at this tension but obviously not ideal, so tomorrow I am going to see if I can get the tension to a normal setting. Hopefully your advice with the bobbin adjustment will help. I am hoping so anyway! I think the techw as in a hurry the last time I got it fixed. He put the new bobbin in and tested it using patterned stitches but not straight ones so maybe the bobbin needed adjusting anyway. Just hope its nothing else amiss at this stage. I will let you know how it goes anyway xx
