thread bunching up
I have a singer prelude sewing machine.
When I start sewing my thread keeps bunching up underneath my fabric wich locks up my needle.
If I look at the problem closer, seems that my upper thread is getting stuck around my bobin hook.
Please help, I've tried everything!
I've cleaned/lubricated my hook/bobbin area.
I've played around with my tension
I don't know what to do anymore...
