Review on 🧵 Prewound 90 Weight Thread Embroidery Bobbins: Size A Class 15 Style 15J for Brother Baby Lock SA156 - Pack of 20 by Carla Anderson

I've been using this for a long time and I like it. This last batch is not so much. Before I get to the point where the machine reports that the bobbin is empty, two threads come loose from the bobbin, causing the machine to always stop. Somehow the filament was not caught while winding the bobbin and tangled with the filament coming off the bobbin causing chaos. I am giving no notification that this will happen until it happens. I used 4 rolls in this order and all 4 were like this.
