Different Sewing Machine Problems With Tension

When sewing machine tension isn’t set correctly, it can lead to various issues in your stitches. Here are common problems you might encounter:

Problem	Description
Loose Stitches	If your stitches are loose and sloppy, it indicates that the upper tension is too low. This allows too much thread from the bobbin to be pulled up into the fabric.
Tight Stitches	Conversely, tight stitches occur when the upper tension is too high, pulling too much thread from the needle down into the fabric, causing it to pucker and bunch up.
Uneven Stitches	Uneven stitches happen when there’s a discrepancy in tension between the upper and lower threads. This can be caused by incorrect threading or improper bobbin tension.
Skipped Stitches	Skipped stitches occur when the needle fails to pick up the bobbin thread, resulting in gaps in the stitching. This can be caused by tension imbalance, dull needles, or incorrect needle size.
Thread Breakage	Thread breakage can occur due to excessive tension on either the upper or lower thread. This can be caused by tangled thread, improper threading, or a dull needle.
Thread Nesting	Sometimes referred to as bird’s nesting, this happens when the upper thread gets tangled underneath the fabric. It’s often caused by incorrect threading or tension issues.
Fabric Pulling	Excessive fabric pulling occurs when there’s too much tension on the upper thread, causing the fabric to be dragged and potentially damaged during the sewing process.

For instance if you’re sewing and notice the stitches are consistently loose, try adjusting the upper tension slightly higher until the stitches become tighter and more secure. If you encounter skipped stitches, check for tension imbalances or try changing to a new, sharper needle.
