I seem to learn the hard way. I tend to not see certain details of items when I am ordering things for the first time, and I did it with my order of thread.
I ordered SimThread black and white 5500 yard spools. One black and one white.
Well, they cannot fit in my Singer Quantum Stylist 9960, as they are too wide and long. I am guessing I need to stay with bobbins with 1500 yards or less.
I also didn't realize this was polyester thread.
Anyway, no way to use it, so maybe someone out there likes this type of thread. Just PM me. All I want is you to pay shipping.
I just ordered Connecting threads salt and pepper set that is 1500 yard size. Based on what I can see, that size bobbin should fit my machine, and they are filled with cotton thread.
