I brought a babylock last december and every time I change thread I have tension problems. I have taken it back 3 times to be worked on. Of course they never tell me the problem but they are good about repairing it. I really would like to take it back for goodbut feel too embarrassed to do so. I have a singer that I have had for over 3o years so I think I will go back to it. My husband would never touch my machine!
