Sewing machine won't feed
I am not really a sewer. I have a Brother machine that is around 15 years old -- model XL2010. I use the machine once or twice per year. Now, it won't feed the fabric. The thread gets tangled up but does not get tight. When I pull the balled up thread out, the machine and bobbin thread look fine. In the manual, I did everything to correct the problem. I rethreaded the machine, rethreaded the bobbin, checked the bobbin, checked the tension, stitch length and changed the needle (nothing looked wrong with the old needle). The needle is correct for the fabric.
This must be something pretty simple. Can anyone help with a suggestion? Thanks.
