I can hardly believe my eyes, but I have a bobbin disaster. I am using a bobbin thread (new brand) and it is blowing out the sides of my bobbins. All of the bobbins in the photo used to be the same size before I loaded on this thread! I have a stand alone bobbin winder that I have used for years (even when longarming, so it has seen plenty of use) and I’ve used bobbin thread for years (a different brand) but I’ve never seen anything like this before! Yikes!
I did get a decent bobbin wound by using the winder on the sewing machine, and don’t ask me how or why it worked because I have no idea. I wound the thread off the bobbin you see to the far right in the photo – and this is what was left on it after the other bobbin was full.
