Thread bunching up on bottom of fabric


Remove the top thread from your machine (NOTE: ALWAYS clip the thread next to the spool, lift the presser foot, and gently pull the top thread down from top to bottom!!! This helps reduce the chances of breaking something by pulling the thread upwards!)

ALWAYS RAISE the presser foot and rethread the top thread from beginning. Verify the thread path is correct and start out with the thread tension set at the midway point (and then tweak the top thread tension through testing).

FWIW, if the thread problem appears under the fabric, it is generally a top thread issue. If the thread problem appears on the top of the fabric, it is generally a bobbin thread issue.

I'm having trouble properly threading my Elna 1010. Could you please help? The bobbin thread keeps bunching up and breaking


bunching of thread under the material is an indication of insufficient tension of the needle thread
increase the needle tension until the threads meet at the center of the materialbeing sewn

Why does bobbin cotton keep bunching?


Is it the upper thread bunching under the fabric? If so, it is usually incorrect upper threading, the thread is not seated in the tension disk, or the upper tension is too loose. Also, a damaged needle can cause issues.

Install a brand new needle that is compatible with the thread and fabric. Frequent changing of needles is an inexpensive fix for a frequent sewing issues.
All About Needles

Remove all the upper thread.
RAISE the presser foot and rethread from the beginning.
Make sure the thread path is correct (consult the manual).
Set the upper tension at the midway point between high & low numbers.

Retest. If the upper thread and bobbin thread are not meeting in the middle of the fabric stitched, then loosen or tighten the upper tension until it does.

NOTE: Always thread the upper thread with the presser foot in the raised position. This opens the disk and allows the thread to seat properly. Also to remove upper thread, it is best to clip the thread near the spool, raise the presser foot, and graspl the clipped thread tail near the needle and pull DOWN through the machine (Never pull thread up through the tension disk).

Noted that you cleaned the bobbin area, but also be sure to clean the feed dogs. Frequently, lint & dust accumulates in and around the teeth which can inhibit their ability to grasp the fabric firmly. Frequent cleaning in this area is important for your machine's maintenance.

Review the cleaning and oiling instructions in your manual. Oiling is important and should be performed frequently with 1-2 drops each spot as specified. Oiling the hook is usually good to do every 8 hours of sewing time. Use ONLY fresh good quality sewing machine oil for your machine--NOT 3-in-1, WD-40, cooking oil, or the old metal can in grandma's sewing basket.

What is the factory tension setting for the Brother LS-2125i sewing machine?


you probably wont find it listed anywhere as it is from experience and changes with different material thickness and needle size
SO how to set tension
thread the machine and adjust the tension until you feel a drag on the thread
now thread the needle and sew a piece of scrap material
if the thread bunches up underneath then increase the thread tension until it sews properly
if the bottom thread is pulled to the top or the thread keeps breaking loosen ti off a bit
when the stitch is being properly formed , both bottom and top threads should meet at the center of the two materials being sewn

My machine bunches tread on the bottom of the fabric when sewing. What am I doing wrong. This machine is new to me.


thread bunching under material is an indication that the needle thread is not at the correct tension
tighten up the tension setting until the result is where the both treads meet at the center of the materials being sewn
practice on pieces of scrap until you get it right

Similar issue with bunching on the bottom side of vinyl


when sewing thick fabrics and when using thick threads you will usually need to tighten top tension - on most machines to maximum in order for the machine to pull the thread up into the fabric. you must also use a needle which will slide along the thread when thread is through eye of needle (take needle out of machine, put thread through eye and see if needle will pass freely along thread - if not, use a larger needle)

Thread is bunching underneath fabric


Needle in correct? Be sure your bobbin is not in upside down and turning the wrong way. Possibly the hook that the bobbicase fits in/on has been hit by a needle and caused a burr that is catching the thread as it comes around. The burr would have to be polished off or hook replaced. The machine could be slightly out of time also.
