You may have to care for your sewing needle more than you do now. The state of your sewing needle can affect your sewing way more than you think.
The first is the total number of hours you have used the needle in sewing. The common rule is to change your needle after a total of 8 hours of quilting or sewing.
If you start hearing thuds as the needle pierces the fabric then the needle has become dull.
If you cannot replace your dull sewing needle with a new one immediately, you can sharpen it. One way to sharpen your sewing needle is to use an emery board with a grit number between 800 and 1500.
