What causes Bird Nests?
Posted: 17 August 2015 at 6 a.m.
Unlike the beautiful bird homes outdoors, bird nests while sewing are anything but cute!
Bird nests occur when thread bunches up underneath. This means the top tension is too loose or the bobbin tension it too tight. Here are a few situations which can cause pesky bird nests.
- If your bobbin tension is too loose, extra thread may unwind off the bobbin, which causes a buildup of thread underneath the needle plate. Try tightening the bobbin tension by turning the small screw on the bobbin case a quarter turn clockwise.
- The top thread isn’t threaded correctly. Many times when I experience bird nests while sewing, it’s because I’ve miss-threaded my top thread. The likely culprit: bypassing the thread take up lever. Simply try rethreading your machine (and make sure it’s in the take up lever!).
- Top tension is too loose. If your top tension is too loose the bobbin thread is winning the tug-of-war and you will see excess thread build up under the needle plate. To remedy, increase your top tension in small increments.
We recommend trying one of these solutions at a time. This way you can hopefully find the exact cause of your frustration.
