5 Common Reasons of Seam Puckering

Though, there could be a number of reasons which lead to seam puckering, but you can blame the thread very conveniently because thread is an essential part of any seam.

However, there are some other factors also, which you can not overlook either.

It could be :-

1. Fabric is too thin or stretchy

Fabric material that you are using. The kind of fabric – thin or sturdy may make the difference in seam finish.

2.Stitch length and width is not adjusted

The width and length of seam you have chosen while handling a particular type of fabric.

3.Thread is not right for the fabric

Do you know, threads come in different thickness or weight according to thickness of fabric, thread weight is chosen.

Then, you have different types of threads – cotton, polyester, cotton – polyester mix, silk, zari, nylon etc.

Moreover, make sure you use the same thread in your bobbin as your upper thread.

4. Coordination between needle and thread

Not only this, you have to coordinate thread thickness with the needle thickness as well. Needles are also used considering the fabric thinness or thickness.

5. Sewing machine setting is in tension

If your sewing machine’s tension settings coordination is not done, then it would trouble the stitches.

In short, there has to be a proper coordination between thread, needle, fabric, sewing machine and the way you react to these things.

Five workable solutions To fix Seam Puckering

#1. If Needle is old, replace it with new

  • An old needle is not gold here! Use a new, sharp needle when you start a new sewing project (ideally). 
  • Or change the needle as soon as you find out that it is bent or old enough to be changed.
  • With stretch fabric, first and foremost, you should be using a stretch needle, which is basically a modified ball-point with a more elliptical point.

#2. Set the Thread Tension

  • Seam puckering tends to occur when the thread tension in your sewing machine is too tight. Loosen your upper thread tension to get it right.
  • Also check if the thread is too tight while it pass through the needle.
  • You can resolve this problem by gradually loosening the thread tension (and testing it with a scrap piece of cloth) until your stitches appear nice and flat, without further puckering.
  • The best way to avoid dealing with seam puckering at all is to test the thread tension before you launch into your sewing project.
  • Better to work out the kinks on test cloth than on pricey fabric; when possible, test with a spare scrap of the final fabric.

#3. Sewing Machine is Threaded Properly

  • The machine is not threaded correctly. Different types of machines may have a different method of threading. 
  • You may go through the manual provided by the sewing machine to know which machine you have and what is the method of threading your sewing machine.
  • To make things easier for you, I have added some video tutorials, which you may check out for easy understanding of your sewing machine and it’s parts / functioning.

#4. The needle is not too heavy for the fabric

  • Needle comes in different sizes and thickness. Rule of thumb is thinner needle for fine fabric and thicker needle for thick fabric.
  • You can easily go by the numbers in increasing order when needing needle for a thicker fabric. Likewise, choose lower number of needle for fine fabrics.
  • Generally, number 11 is used for fine fabrics and 16 is used for cottons.

    For denims or thicker fabrics, you can choose number 18 needle for your everyday sewing.

#5. Coordination between needle, thread and fabric

  • Shorten your stitch length according to the fabric.
  • If the stitches are too coarse for the fabric being sewn, keep a thin sheet of paper underneath the fabric to prevent puckering.
  • You can attach interfacing to your fabric to avoid seam puckering.

How to use interfacing

  • When sewing extremely light weight materials, place a sheet of paper underneath the fabric.
  • One more thing, don’t pull on your fabric as you sew.

    This will help you handle the fabric well and get a smoother seam.
