Which stitch should I use? A beginner's guide to picking outline stitches
Every embroidery pattern is mostly lines: stems, vines, lettering, the outline of a leaf. And almost every line you'll ever stitch is one of four stitches — stem, back, chain, or running. They are all "a line", but they behave so differently that picking the right one changes how finished a piece looks more than almost anything else you can do.
Here is the same wavy line worked in all four, so you can compare them side by side:
Stem stitch: the one for curves
Stem stitch is the queen of flowing lines. Each stitch overlaps the last by about half its length, always coming up on the same side of the previous stitch, and the overlaps twist together into a gentle rope. That rope is what makes it magic on curves — flower stems, tendrils, swirly lettering — because the line stays smooth and slightly raised instead of turning into a chain of straight segments.
Two habits make stem stitch behave. First, keep your working thread on the same side of the needle for the whole line (traditionally below the line when stitching left to right); switching sides mid-line breaks the rope and leaves a visible kink. Second, shorten your stitches on tight curves — long stitches will cut the corner and flatten your beautiful arc.
Back stitch: the one for precision
Back stitch gives you an unbroken, crisp line: come up a stitch-length ahead, then stitch backwards into the end of the previous stitch. Because every stitch shares a hole with its neighbour, there are no gaps, and — unlike stem stitch — it turns sharp corners without complaint. That makes it the default for anything that needs accuracy: small lettering, geometric borders, tiny details like whiskers or window frames.
Its personality is plainer than stem stitch, which is exactly why it works there. It's also the foundation for a family of pretty variants: whip a second thread through the finished stitches and you get a candy-cane whipped back stitch that curves almost as nicely as stem.
Chain stitch: the one for weight
Chain stitch is a series of little loops, each one anchored by the next. The result is the boldest line of the four — wide, dimensional, slightly nubbly, closer to a drawn marker line than a pen line. Reach for it when a line has to carry visual weight: thick lettering, the outline of a hoop design, borders, or anywhere a stem or back stitch would look anaemic.
Because it's wide, chain stitch is forgiving of slightly wobbly stitching — the texture hides small irregularities. It also fills space fast: rows of chain stitch worked next to each other are a classic, sturdy filling. The trade-off is detail; on very tight curves or small letters the loops crowd each other, so drop down to back stitch when things get fiddly.
Running stitch: the one for lightness
Running stitch is the simplest stitch there is — in and out, leaving even dashes. Don't let the simplicity fool you: those dashes are a deliberate texture. A dashed line reads as quieter and lighter than a solid one, which makes running stitch perfect for background details, suggestion rather than statement — falling snow, water ripples, quilted texture in the style of sashiko, or a subtle inner echo line inside a bolder outline.
It's also by far the fastest of the four, which matters on long decorative lines. Keep the stitches and the gaps consistent; the evenness is the beauty.
Choosing in five seconds
- Curvy and flowing? Stem stitch.
- Small, sharp, or precise? Back stitch.
- Needs to be bold? Chain stitch.
- Should whisper, not shout? Running stitch.
One more lever worth remembering: strand count. All four stitches change character when you split your six-stranded floss — two strands of back stitch is delicate enough for the tiniest lettering, while six strands of chain is practically a cord. In Stitch Studio App every line element has a stitch and a strands setting, so you can try the same path all four ways before you ever thread a needle — the preview above is generated by the same engine that renders your own designs.
