I tried to sew a buttonhole using my brother XL-2220 machine. The left and right zig zag stitches are of different tightness. The left side is too coarse (stitches wide apart) and right side is tighter (and looks like that of a regular buttonhole). I tried to adjust the buttonhole fine adjusting screw but I think it only changed the right hand stitches. How can I adjust the left hand stitches so that they look correct, like the right hand stitches?

your machine might have a problem with the rotary hook, it might need to get timed by a professional.

The brother website has a users manual for it that can be downloaded. Use this link to get it:

SOURCE: zig zag stitches are not holding

When ever a machine is jamming up the bobbin thread, it is a result of your top tension. It is either set to low (under 4), or the thread has come out of the take-up lever. Check your threading, fromt he spool pin, down to 2 and up to 3. Three is the take up lever. From the take-up lever down to 4. Set the thread behind the thread guide and thread the needle form front to back. Low quailtu thread 9dual duty or all purpose) can also create this problem.

SOURCE: my zig zag stitch is distorted on the top side but

The bobbin tension sounds too loose. This will help if you have a bobbin case and not a drop in bobbin. Let me know if you have a drop in bobbin:
Setting bobbin case tension:
Put wound bobbin in bobbin case. Thread it in case. Hold the thread and carefully let go of the case only holding bobbin thread. The case should NOT move. Quickly let your hand drop 2-3 inches to let the bobbin case free fall for 2-3 inches, the bobbin case should move slightly then stop. It moves because it let’s a little thread off the bobbin. It should then stop .5"- 2" of thread should release. If so, your bobbin case tension is right. If it’s right then begin to look at your top thread tension. Always Always start with a properly adjusted bobbin case, then adjust your top tension accordingly.

Hello,
Try these solutions.

* Re-thread your needle
It may be threaded incorrectly (backwards).

* Reinsert your needle
Make sure it goes all the way into the holder and that it’s positioned correctly – usually with the
flat side away from the bobbin, but consult your machine’s manual to be sure.

*Change your needle
Your needle may be blunt, bent, or otherwise damaged.

*Your fabric may require a different needle. Generally, heavier fabrics require larger needles and
thinner fabrics, smaller needles. You may also need a larger needle if
you’re sewing through many layers of fabric. And make sure to use a ballpoint needle for knit fabrics and a sharp needle for wovens (or a universal needle for either).
And make sure your needle is appropriate for the type of thread you’re using.

* Adjust the pressure of your pressure foot
It may be too light for your fabric.

* Change your thread
If your upper thread and bobbin threads are different types, try using the same thread for
both. And use a good quality, brand name thread.

* Adjust your thread tension
It may be too tight or too loose.

* Re-thread your machine
It may be threaded incorrectly.

* Change your needle plate
Try switching to a needle plate with a smaller hole (a straight stitch needle plate).

Important: If you change your needle plate, check to make sure your needle aligns perfectly with
this smaller hole before starting to sew. A misaligned needle could hit the plate and break, which
could be dangerous. And make sure to change your needle plate back for zigzag and other wide
stitches.
I hope this helps you.
