Thread on my consew 225 keeps balling the thread on the bottbottom

Sounds like bird nesting. The upper thread accumulates under the fabric creating a series of loops and knots.

First: Install a brand new needle and make sure it is installed facing the correct direction. (A new needle is the least expensive fix for most sewing machine issues.)

Second: Remove the thread. RAISE the presser foot and rethread from the beginning. Make sure it is threaded correctly (consult the owner's manual).

Third: Pull up the bobbin thread through the fabric and gently hold the thread tails in your left hand while slowly taking the first couple of stitches.

Thread is getting bunched up in machine

First thing: install a brand new needle.
Second: remove upper thread. RAISE the presser foot and rethread from the beginning. Set upper tension to the midway point between high & low numbers.

When i run a straight stitch, the top of the fabric looks well sewn; the thread on the bottom of the fabric, however, bunches up-it looks nothing like the top stitch.

Is it really the bobbin thread that is bunching under the fabric, or is it really the top thread that is creating loops and "bird nests" under the fabric???

Rethread your upper thread. BEFORE you thread the upper thread, be sure to RAISE the presser foot. This releases the upper thread tension disks so the thread is firmly seated in the tension disk.

If it continues to be a problem, then the upper tension needs to be tightened. Adjust slightly, then test. Repeat until the upper and lower threads meet in the middle of the fabric.

Top thread bunching under fabric when sewing

tension could be too loose. start with bobbin tension- should allow thread to pass with SLIGHT resistance. then adjust top tension at about 2-3 to start.

The thread bunches up under the fabric

Your bobbin cotton is probably wound on too tightly

The tension is off ?? bottom thread bunches

Sounds like it could be! Probably worth trying to readjust it. Are you using a fine fabric too? That can cause bunching.

The string under the fabric bunches up until its in a big tangle and I have to ripe the fabric out from underthe needle and cut all this bunched up string from machine and fabric

Make sure bobbin is placed correctly and has tension. Make sure your getting tension from upper tension when putting pressure foot down, pull thread to make sure there is tension present and set tension to 4

IDT foot bunching up fabric

Hi Gramma Rosie,

The bunching up of fabric is due to either:

1. Obstruction in front where the fabric has to move forward (in which case you should tug a bit on the front end of the fabric as it goes ahead.)

2. The pressure foot (that pinches the fabric between the advancer teeth and itself), is either too loose or too tight. (It depends on how thick is the fabric and how many layers of fabric are you trying to pas between the IDT foot and advancer teeth) For that you need to tighten or loosen the rotary bolt on top. Its generally connected to the foot like a shock absorber having a high tension spring.

3. The fabric advancer teeth are not moving sufficiently. This you need to rectify by adjusting the up-down lever at the right that is rsponsible for fast & slow advancing of the cloth & accordingly the stitches will be longer or shorter.

I don't think it should be too much of a task for you to solve.

Good luck Rosie.
