What happens if you use the wrong size bobbin?
The short answer is YES! Filling a sewing machine bobbin too tightly can make a plastic bobbin bulge or stretch the thread if you are using a metal bobbin. This may be hard to see but can cause all kinds of problems. Plastic bobbins can become compressed in the center causing the bobbin to distort.
If you try to place a metal bobbin in a plastic bobbin case you may see that the bobbin case wears out a lot faster than it is supposed to. That will cost you more money than you are ready to spend. While metal is always better than plastic, it is just not a universal sewing material that has unlimited uses.
