Tension issue, I think. You should be able to find a video on how to adjust the tension for your machine online or it should be in your manual. Also make sure the thread on your bobbin is wound tight. Tension issues are a pain in the behind. Good luck!

Either way it is an awesome book. Hope you enjoy it. 🙂

I loved his book! I actually listened to it on audiobook because I love his voice. He did such a great job. 😁
