When should you replace your bobbin case? 👀🧵
If you notice any of these signs, it may be time for a replacement:
🔹 Broken tension spring — damage to the tension spring can affect thread flow and tension.
🔹 Rust or buildup — check both the inside and outside of your bobbin case. Lint, loose threads, dirt, or rust can interfere with smooth operation. If the case is rusty, replacing it is the best solution.
🔹 Broken tension plate — a damaged tension plate can lead to inconsistent tension and stitching issues.
Small component. Big impact on your stitches. 🧵
