Running stitch
A running stitch is a single line of evenly spaced stitches that follows a path. It is used for outlines, thin details, hidden base stitching and travel between parts of a design.
A running stitch is the simplest stitch a machine makes. The needle goes down, the fabric moves a set distance, and the needle goes down again, repeating along a line or curve. It is part of the stitch file, set when the design was digitized, and the machine just follows the points it is given.
It matters because it does several jobs. Digitizers use it for outlines, thin lines and fine detail, and for the hidden base stitching under satin and fill areas. It can also carry the thread between parts of a design instead of leaving a long loose jump, which Ink/Stitch does inside fills with what it calls travel stitches. A plain run is only one strand of thread wide, so on its own it can look thin.
Stitch length is the main setting you can change in digitizing software. Ink/Stitch sets it in millimeters, and one density guide lists running stitch at 2.5 mm, about 0.1 in. Shorter stitches follow curves more smoothly. Longer ones look looser and can cut across tight corners, which is why Ink/Stitch also has a tolerance setting that controls how far the stitches may drift from the drawn line. To make a line bolder, many digitizers use a bean stitch, where each stitch is sewn forward, back and forward again. Software names vary, so look for bean, triple or similar wording.
Common mistakes: leaving a thin line as a single plain run when it needs to stand out; picking a stitch length too long for a curve, so it looks angular; and shrinking a design so far that stitches become tiny. Stitches under 0.3 mm are a known cause of thread breaks, and scaling down can create them. Keep resizing modest: OESD recommends staying within about 20 percent up or down, and says formats like DST and EXP do not adjust stitch counts when resized.
Example: A 2 in (51 mm) outline sewn with 0.1 in (2.5 mm) stitches takes about 20 stitches. The same line as a bean stitch with one repeat sews each stitch three times, so about 60 short passes along the same path. Both are illustrative numbers, not rules.

Frequently asked questions
What stitch length should a running stitch be?
There is no single right number. One digitizing guide's density table uses 2.5 mm (about 0.1 in) for running stitch, and Ink/Stitch lets you set any length in millimeters. Shorter follows curves better, longer looks looser. Start near that figure and adjust on a scrap.
How do I make a running stitch line look thicker?
Use a bean stitch, which sews each stitch back and forth so the line looks wider. In Ink/Stitch a repeat setting of 1 sews each stitch three times. This is set in the editable design, not on the machine.
Why do very short stitches cause thread breaks?
Stitch Toolbox flags stitches shorter than 0.3 mm and says they cause most thread breaks. Scaling a design down can shrink stitches below that point.
