Review on PreWound Bobbins Embroidery Machines Babylock Sewing by Sharon Weston

Bobbins where I can find the end of the thread, five stars. However, I can't find the beginning of the thread in a large percentage of them. Maybe half of it. I've had the box for over two years now and I've noticed that some bobbins loosen the beginning of the thread. So when I need a new spool, I shake the box in hopes of knocking the thread out. Many still haven't unraveled, others are coiled so the beginning of the thread gets caught under the coiled threads and I can't unravel it to unravel it freely.
