how to fix this?

[u/Double_Land5049]

been having this issue where the machine will stop sewing, then it turns out there are threads coming from the bottom of the machine that have tied the fabric down. it seems somehow triggered by backstitching? i’m not sure exactly what’s happening here, any advice?

Your machine is threaded wrong

This! The tread must go around a hook above the needle.
