Q:

What is the reason my machine is creating uneven stitches?

A:

The most common reason for uneven stitches is old or inferior thread. Another cause for uneven stitches is the fabric is being pulled while sewing. When sewing it is important to remember to never pull the fabric - allow the fabric to be taken up by the sewing machine.
