STITCH QUALITY
How Tension Affects Loops, Puckering, and Thread Visibility
Quick Answer
Read both sides of the embroidery before blaming tension. Similar symptoms can come from the file, hooping, backing, thread or needle. Change only settings allowed by the model manual and compare one change at a time.
What balanced tension means
Judge thread appearance from both sides and the finished fabric shape. A good front alone does not show whether the whole setup is acceptable.
Keep the file, material, backing, thread, needle and machine state unchanged while comparing one approved control change. Record the change and the resulting appearance on both sides.
- Inspect front and reverse together
- Control all non tension variables
- Escalate model specific settings and mechanical causes
Read the front and reverse side
Record loops, bobbin visibility, puckering and where they occur. Compare them with the approved sample before changing settings.
Make only documented adjustments permitted by the exact manual. If the symptom returns or changes unpredictably, keep the sample and request help with the model, revision, setup and evidence.
- Inspect front and reverse together
- Control all non tension variables
- Escalate model specific settings and mechanical causes
Separate tension from design and hooping causes
Check design load, backing, hooping, thread and needle as separate possible causes. Similar symptoms do not prove a tension fault.
Keep the file, material, backing, thread, needle and machine state unchanged while comparing one approved control change. Record the change and the resulting appearance on both sides.

- Control all non tension variables
- Escalate model specific settings and mechanical causes
One variable test method
Change only a setting allowed by the exact model manual. Keep the file and materials unchanged and compare the resulting sample.
Make only documented adjustments permitted by the exact manual. If the symptom returns or changes unpredictably, keep the sample and request help with the model, revision, setup and evidence.
- Inspect front and reverse together
- Control all non tension variables
- Escalate model specific settings and mechanical causes
Record acceptable range
Record the approved setup and sample rather than publishing a universal tension value. State which file and materials the result applies to.
Use controlled samples to agree an acceptable visual result. Stop if the next step requires an unconfirmed model value, bobbin case service or mechanical adjustment outside the approved instructions.
- Inspect front and reverse together
- Control all non tension variables
- Escalate model specific settings and mechanical causes
Model specific escalation
Preserve the failed sample and setup record if problems continue. Ask for model specific guidance before mechanical adjustment or protected service work.
Make only documented adjustments permitted by the exact manual. If the symptom returns or changes unpredictably, keep the sample and request help with the model, revision, setup and evidence.

Frequently asked questions
Why do I need a production sample?
Loops, puckering or visible bobbin thread can have more than one cause. Check the file, fabric, backing, hooping, needle, thread and settings together. Change one permitted setting at a time and compare samples.
What should I share with FUJA?
Record where the issue appears and keep front and reverse photos. Include the design, material, thread, needle and settings, and note each change and its sample result.
