I have a Singer Advance as I was sewing along I broke a needle I do not know why I didn't have any pins are anything to hit. My machine was working fine untill then. I changed needles and when I start sewing it grabs the material and makes a big mess so I cleaned the bobbin area, changed the needle again checked to make sure threaded correctlytried again same problem I have also tried diffrent threads making sure to use same thread in bobbin and on top. Now I can get the machine to sew about 10 stiches then it makes a big mess on bottom and I can bearly get the fabric off the machine. Do you have any more suggestions as to what might be wrong and how to fix it.
