I hope some of you who have this machine or one similar can give me some advice. I have the opportunity to buy this machine for a really good price. The current owner said it could probably use a tune-up, as she had some problems with tension the last time she used it, but that may have been due to the type of fabric she was using and her own inexperience.
So my question – what is the best way for me to test the tension when I go see the machine? I will of course bring some cotton to sew, and maybe a block with batting to see how it sews through the layers. I am a little leery of taking it on if it has serious issues, but if she was sewing something really unusual it might not be surprising that she had trouble, and it may not be a tension problem.
Any thoughts you have would be appreciated!
