Puckering is usually a result of incorrect tension, ie too tight. Be sure you are using a new needle and thread that are compatible with the fabric you are stitching. A heavier thread like Coats & Clark cotton-wrapped polyester may be too thick for sewing silk. Another thing you may want to check is the presser foot pressure adjustment (the amount of pressure the presser foot applies to the fabric and feed dogs). This should be discussed in your user's manual. Something else that may help is using a walking foot or teflon foot that allows the fabric to advance smoother, rather than the presser foot "pushing" the fabric as it advances through the machine.

Another thing that may be contributory is the type of fabric. Some fine fabrics, ie silk, chiffon, have a natural tendency to pucker.

What is seam pucker Types of seam pucker with causes and remedies

First, install a brand new needle. Confirm that you are using the correct needle for the thread and fabric being stitched, ie the needle eye could be too small for the thread, the fabric is coarse or sticky causing the thread to wear/fray causing breakage, the needle is blunt or bent, a ball point needle is being used on woven fabric or vice versa...

Second, remove the thread from the machine. Always RAISE the presser foot and rethread from the beginning--make sure the correct thread pathway is followed (consult the manual).

Verify that the tension is not set too tight. The tension is correct when both upper and bobbin threads meet in the middle of the fabric without any puckering of the fabric.

Use good quality thread--avoid old or bargain bin variety. And, use the same thread for the upper and bobbin. Some thread brands may work better than others in your machine. You may need to experiment to find ones that work best.

There is also the possibility that there is a nick or burr somewhere that is catching the thread. You can wrap your index finger with old hosiery (or similar fine fabric) and rub around the thread path, in the bobbin/hook area, needle plate, etc. A small burr can be smoothed with a fine emery board. A big burr may require replacement of the part or service by a technician.

If the fabric is puckering when you sew, it is most likely because the thread tension is too tight. Make sure you are using a brand-new needle compatible with your fabric--using a 70 or 80 needle and a lighter weight thread may work better as a 90 or higher needle is big enough that it can stretch the fabric before penetrating it, causing puckering.. Puckering also occurs more frequently when sewing light-weight fabrics and may necessitate using a walking foot or a stabilizer to help give the fabric more body as it is stitched (wash-away stabilizer would probably be good when sewing washable fabrics). Another thing that may cause puckering is when the bobbin is wound at a fast speed. Slowing down when winding the bobbin will reduce the amount of stretch added to the bobbin thread. If it is stretched going onto the bobbin, it will shrink back up when it is stitched to your fabric. Also check whether your machine has a presser foot pressure adjustment. The pressure should be lighter when sewing finer fabrics, ie silk, and heavier when sewing thicker fabrics like wool or denim.

Stitching is puckering on lightweight fabric SEWING IN GENERAL

Tension is a balancing act between the upper tension and the bobbin tension. Balanced tension (which is not always necessary) is when the two threads meet between the layers of fabric. Not all unbalanced stitches are a tension problem. You can have loops under the fabric from a failed take up lever, improper clearance between the positioning finger or even a burr or lint. First I check the upper tension. If you can not make the upper tension normal pinching the thread after it comes off the spool will act as a tension device. If this solves your problem then start with cleaning.

You may have lint between the tension discs at the top next to the take up lever. Clean this out with the presser foot up. Next install a new needle size 80 and thread the machine. When you lower the presser foot and pull the thread the spring steel the needle is made of should bend 1/8 of an inch at normal tension. Between 3-5. If this does not happen turn to a larger number on the tension assembly. If this does not deflect the needle as you pull the thread to the left rear of the machine your tension assembly needs repair or replacement.

The bobbin tension is controlled by a spring on the bobbin case or bobbin basket (depends on the sewing machine). This spring can also get lint under it. The lint can hold the tension discs open causing no tension. This may be the problem if you see the lower thread pulling up to the top of the fabric. Normal tension on the lower thread is usually 150-200 grains. That may not mean much to you and you may not have a scale to measure that. One simple trick is to take a wooden clothes pin and glue 3 pennies to it. I then use this as a weight to set the bobbin tension. I clip the clothes pin to the thread and set it on the work bench. Next raise the bobbin case or bobbin basket without touching the thread or bobbin. Then tighten the tension screw on the bobbin case until the clothes pin lifts off the work bench.

This gives you a good place to start on balancing the tensions. Set up a straight stitch at the mid range of 2-3mm long and sew. Turn the upper tension dial to the mid range 3-5 and observe the stitch. If the bottom of the fabric shows too much top thread tighten the upper tension. If the top of the fabric shows too much lower thread loosen the upper tension. I recommend playing with your tensions to learn what too loose and too tight a tension look like. Sometimes we want the upper tension really loose to do a basting stitch. If you want to pucker (gather) you can create a long stitch and play with the tensions. A tight upper tension will pucker thin fabric. You can also gather fabric manually by using a long stitch and a loose upper tension then bunch the fabric together on the loose threads.

After all that it may be easier to take this to your local dealer and ask for advice.
Have a great day and keep on sewing.

Check tension and threading up first, sounds like top tension or thread catching somewhere. Also have you changed the needle, i change mine for EACH new sewing project, needles go blunt and need replacing every 4-6 hours of sewing. Lastly, press seams as you go, this improves appearance and blends stitching into the fabric,

Recheck the tension on the top thread. Test it before you put it through the needle to see if there's any tension. It should pull but with some resistance. Also check the needle and make sure it is the right type for the fabric and not bent etc.

Looping on the underside of the stitch is from the upper thread, usually tension problem. But do check the bobbin tension and make sure it isn't too tight, though that's not usually the problem you're describing. The two tensions need to work together in order to get a nice, flat (not puckered or loopy) stitch.

One last thing you might check too, though again this wouldn't typically be the problem - is the dogfeed moving the material along under the presser foot correctly?

Most of the time the problem you're describing is due to not enough tension on the upper thread.

New needle and make sure it is the right sized needle for the fabric that you are sewing. If silky satin then use a size 70 or even 60 needle sharp. If microfibre then there are Schmetz needles called microtec that are perfect for this.

Also try shortening the stitch length a little. You may still need to finesse the tension a bit. I think this is a front loading bobbin machine so you might try adjusting the tension on the bobbin holder a little bit. It is hard with these as there is no "0' marking to set it to, its just trial and testing.

Also, are you pinning across the seam line at about 3 inch intervals?

If there is still some puckering happening, then perhaps, stop at the end of the seam with the needle in the work, and ease the fabric along the stitching line a bit to smooth out the seam, then do the reversing stitches at the end to lock off the seam.

Also press, press, press each seam. Always press on top of the seam, turn it over and press the underside of the seam, then lie right side down on the ironing board and press the seam allowances open. This sets the stitches into the fabric and finishes off the seam appearance. I always sew with the ironing press on beside me.

You may still be unhappy with the seam result after doing all this - if you enjoy sewing then consider shopping for a higher quality machine - there is a difference in stitching quality between a $400 and $2,000 machine. You could always take a piece of your fabric to a sewing dealer near you and test sew on a European machine, you should see a difference in the stitching quality.

a wide zig-zag on a light weight fabric single layer is almost guaranteed to pucker up, just because the thread is under tension and this is often stronger than the fabric being pulled together by the stitches.

However, if a straight seam is puckering, this could be caused by a blunt needle, too big needle, or too tight tension or too long stitch length. You should be able to vary some of these variables to reduce the puckering and improve the stitch appearance. Other things to check might be the top thread being caught up somewhere in the thread path and pulling on the stitching.

If I am finishing the cut edge of aa single layer of light weight fabric I would use a three step zigzag to hold the fabric firmly and neatly.

Hope this helps a little?

1. Make sure your needle is correct for the fabric. Go buy some good needles in several sizes. You'll need a 90 for jeans, rounded points for fine fabrics... get a few sizes. Your manual should provided you with clues to the right needle for the fabrics. (BTW... there really is no such thing as a Universal Needle... toss it.)

2. Re-read your manual and carefully follow the instructions on threading the bobbin and the upper thread...

3. Check your tension on the upper thread... it is too loose for the application. The tension on the bottom thread is handled by a spring on your bobbin case or race. If you do not have that threaded properly you'll have problems. Same with the direction the bobbin turns... have in it backwards... problems.

Barring all these things... It might be time for a qualified Singer repair person to look at it. Sadly Singer has seriously lowered it's standards in the last 20 years.
