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

Yesterday I used the first thread and there was a problem; the bobbin thread was visible from above and below, but I didn't see the upper thread. This is my first time using pre-wound bobbins and I read somewhere that the pre-wound bobbins are full and should work after removing 2-3 arms. So I took a few feet off the reel (at least 8-9 feet) and tried again but that didn't solve the problem. Then I wound my spool with the same thread and tried it later and it turned out great! I'll do that as a workaround from now on. I'm glad I didn't buy a large pack. I have a brother pe-770. Also, the thread looks dull, doesn't have the sheen of embroidery thread, so I'm not sure if it's really under embroidery thread or not.
