    My zig zag is also distorted on top but perfect on the bottom (ditto for overedge). I have the Janome Jem 660 with a drop in bobbin. I have played with the tension (not separate for top and bottom thread) but get the same results.

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.

Singer Sewmate, the zig zag stitch is perfect on the bottom of the fabric, but lopsided on the top, how do I fix this?


This could be a combination of two things, to much down pressure on the spring loaded foot on top or the fabric distorting it, the other is a top stich tension issue adjust tension in and out to see if this improves the stich.
good luck

Upside down stitching


Sounds like the needle alignment is out.
This website has some instructions on how to properly set it up and also has manuals too.

Bernina activa 210 won't zigzag and has bobbin issues on straight stitch


it's very possible that the machine is slightly out of time & needs to be service at a sewing machine shop
is the fabric & thread & needle compatable with each other?
did you use every thread guide when threading the machine?
is the bobbin in correctly?
is the bobbin warped?

The thread underneath when sewing is too loosed


Usually thread too loose on the bottom is caused by the upper tension being too loose. The top and bottom tensions work together with the top thread making the underside of the stitch seem too taunt or too loose and the bobbin thread causing the top side of the stitch to be loopy or too tight. Select a large zig zag stick and sew a couple of inches. Then examine the stitch. It should look identical on both sides. Look to see which side is drawn too tight, the zig zag being smaller on that side with threads from the bottom threads pulled through. Then adjust the two tensions so that they make a uniform, identical stitch.

Also, when the bobbin tension is right you can hold the bobbin dangling by the thread and it won't spool out to the floor but will let loose a bit with a slight flick of the wrist. Too loose it will just spool out. Too tight and it won't drop at all. When you get that set right then do the above zig zag test to see where the top tension should be set.

I'm sewing a zig zag stitch and the underside is a perfect zig zag and the upper side looks like it should be the underside....how can I fix this so that the beautiful zig zag is on the top?


FIRST > Make sure your bobbin case is threaded correctly...

NEXT
For normal straight sewing the top tension should be around 5, for zigzag or satin stitch you need to lower your upper thread tension a bit. Try it at 4, if it still pulls your bottom thread to the top try it at 3 etc...

What are the settings for regular sewing, I do not have a manual. It has 3 knobs on the front and 1 on top? This might have something to do with my problems.


The three front dials are as follows....left to right-Stitch width, type of stitch, and stitch length. The dial on the top adjust the top tension.

For straight stitch you want 0 stitch width, straight stitch, 3 for stitch length.

For zig zag you want turn your stitch width to how wide you want the zig zag, choose zig zag stitch, and choose how close you want the stitches to be on the stitch length dial. Practice on a piece of fabric. Usually for zig zag you will want to loosen your top tension a little bit.

Zig zag stitch


If your stitches do not look good on the top side you have a problem with the bottom thread. make sure you have the correct bottom tension: Is the thread under the bobbin tension plate and when you hold the bobbin and case lightly in your hand the tension should be set in a way that there is little resistance , yet still some, when you pull the thread. After you set your bobbin tension, you may have to adjust your top tension to balance. Also make sure the thread comes off of your bobbin the way your manual tells you, clock or counter clock wise.
Make sure your bobbin (plastic) is not sooooo old, buy a new one.
