How does tension affect embroidery?
Proper bobbin tension is essential to good embroidery. If tension is too tight, unwanted bobbin thread may begin to show on top of your garment and you may begin to experience frequent thread breaks which wastes time and money. Bobbin tensions should be 18 to 22 grams (up to 25 grams when embroidering caps).
How do I know if my bobbin tension is correct?
The thread should unwind just slightly and the bobbin case should drop an inch or two. If the thread unwinds without resistance and the case slips to the floor, your bobbin tension is too loose. If the bobbin case doesn’t budge, your bobbin tension is too tight.
Why is my thread bunching underneath?
A: Looping on the underside, or back of the fabric, means the top tension is too loose compared to the bobbin tension, so the bobbin thread is pulling too much top thread underneath. By tightening the top tension, the loops will stop, but the added tension may cause breakage, especially with sensitive threads.
What tension should I use for cotton?

Why are my stitches loose embroidery?
