What is an Embroidery Birds Nest?

Bird nesting (nesting) is when thread bunches in the back side of embroidery, between an embroidered piece and the needle plate. Often top thread catching between the needle plate hole and hook assembly.
It is can ruin an entire embroidery design!

As soon as you can saw problem you need to stop machine. Ether way, machine will take some amount of stabilizer and fabric under plate.

Carefully remove hoop from machine. If nest already in your machine, remove bobbin case and after that carefully pulling hoop with your embroidery. Good if you can pull the nest through needle hole in the throat plate. If nest is big, it can be trapped in the throat plate, needing to be carefully cut and removed threads in the nest and after that pullout hoop.

Sometimes you can’t remove hoop without damaging of embroidery and fabric. Sometimes we can fix this hole, but sometimes we are need to through away everything.
Can be many reasons for bird nesting, I will explain some of them.

    1. Tension problems. A tight bobbin tension, together with highly loose needle thread tension.
    2. Improperly inserted or threaded bobbin.
    3. Incorrectly threaded upper thread. On some one needle machines birdnesting happens when the thread somewhere jumps out and it reduces tension on the thread.
    4. Flagging. It’s occurs when the fabric is hooped too loosely, the hoop bounces up and down during sewing. Flagging occurs if the fabric does not release from the needle; it is instead pulled up on the upstroke of the needle. It’s can be happened during stitching FSL designs (adhesives creates a buildup and stabilizer and fabric go up with needle) or than machine do not cut (trim) thread properly (if your machine has this feature).

Few recommendations:

  • Always check the bobbin case for proper tension. Design density may affect looping and bird nesting.
  • A short embroidery stitch and tight (high) density may have big problem for your embroidery.
  • Good designer always removes short stitches in design and create objects without sharp points.
  • The eye size of the needle could also affect bird nesting. Do not use sewing needle for embroidery! The most common embroidery rayon and poly thread is 40 wt (rayon usually a little thicker than poly). These threads perfectly go through the eye of 70/10 to 75/11 size needle.
  • Only if you are using thread 30 gauge, consider switching or 80/12 needle!
  • Working with metallic threads, consider using an 80/12 or 90/14 needle (My machine perfectly stitching by metallic thread by using 75/11 size needle.)
