To create a running stitch, begin by bringing your needle up through the fabric at the beginning of your line, pulling the thread through but leaving a tail at the back for securing as you work (as shown in 'getting started').

Push the needle back into the fabric a short way further along the line depending upon the length of the stitch that you want to create and bring it back up again before pulling the thread through (as shown below).  Try to keep your stitches the same distance apart as they are in length to make the work neat (unless you are purposefully making different length stitches for a decorative effect that you want to achieve!).

Continue to follow your line until you reach the end. 

Secure your thread at the back by weaving it into the back of the stitches that you have sewn.
