How do I adjust the tension on my Overlocker?
Start sewing, and slowly turn the tension dial for one of the threads to a lower number. As you sew, examine the stitches to see the change in tension. The thread that has been adjusted will be slack or loose. Return the tension dial to the original setting.
Why is the back of my stitching loose?
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.
Why does my Overlocker skip stitches?
Machine skips stitches . Insert a new needle – it may be bent or blunt and Insert needle correctly. Wrong needle size – Change needle to correct size for fabric thickness. Check threading – Rethread with care.
How do you know thread tension is correct?
To test if the tension is correct, insert a bobbin in the bobbin case. Then hold it up by just the thread, the bobbin case shouldn’t move. Give a little jerk on the thread and if the bobbin case slides down slightly, then the tension if perfect. If it drops freely, then it’s too loose.
Why does the thread bunch up underneath?
Your Thread Tails Are Too Short
If the thread tails that come out of your bobbin are shorter than two inches, they may get sucked into your sewing machine when you begin to sew. This can cause thread bunching underneath your fabric.
Why is my serger bunching up?

The average stitch length is 2.5mm. This is the typical setting on newer sewing machines. Older machines usually give you a range of about 4 to 60 which tells you how many stitches per inch; the equivalent of 2.5mm is about 10-12 stitches per inch.
What is stitch depth?
Stitch depth is the distance between a stitch’s upper and lower surfaces. Stitch consistency is the regularity of how each stitch is formed in a row of stitches and is important not only for the structural integrity of a garment, but also for its appearance.
