Short answer: A bird nest is a tangle of top thread under the fabric. It is almost always a top-thread problem — the thread is not seated in the tension discs, so it has no tension and loops underneath. Rethread with the presser foot / take-up in the right position, check the bobbin is seated, and make sure the fabric is hooped drum-tight so it does not flag.
| Cause | Fix |
|---|
| Top thread not in tension discs | Rethread the whole path, floss it into the discs |
| Fabric flagging (bouncing) | Hoop tighter; use correct backing; magnetic hoops help |
| Bobbin not seated / wrong way | Reinsert bobbin; check case tension |
| Thread tail too short | Leave a longer tail at start |
| Hook timing or burr | Service the machine |
FAQ
Is bird nesting a bobbin problem?
Rarely — it usually means the top thread has no tension. Rethread first.
How do I remove a bird nest?
Snip the threads carefully from underneath; never pull hard or you can damage the hook.
Why does it happen on caps?
Cap fabric can flag if the cap frame is loose; tighten the strap and use cap backing.
When should I call a tech?
If nests continue after rethreading and new bobbins, timing may need adjustment.
