Here is a quick tip for you - and anyone you are mentoring into being a quilter!
Don't overfill your bobbin.
Be sure that the bobbin thread, when wound, is well within the edges of the bobbin itself. Not bulging out or stacked so full that the thread goes beyond the bobbin edge at any point.
Your bobbin needs to spin freely within the bobbin case. And some sensors may trip a warning if they see too much thread.
Wind your bobbin snugly - I run the thread, while loading, between my thumb and forefinger to make sure it has even tension and is loading the bobbin evenly. I know that sounds a little compulsive, but it works really well. And if the bobbin thread pops off the guides I am already holding it so it doesn't wrap around the spindle.
You probably can't get as much thread on the bobbin as they do at a factory that loads prewound bobbins. Don't worry about that and don't go for the record...
Bobbin winding is a little Zen moment during the quilting process that reminds you to slow down and enjoy the meeting of needle, thread, fabric, and your own creativity. Be mindful and have fun!
