An embroidery machine has one tool: a needle that goes up and down through fabric, dragging thread. Everything you see in an embroidered logo - the glossy lettering, the solid filled shapes, the fine outlines - is just different ways of arranging those needle penetrations. Digitizers describe four core stitch types plus a handful of specialty variants. Below is the working reference.
Satin Stitch

Satin stitch is the glossy, smooth, parallel-stitch finish you see on almost every embroidered logo letter and narrow design element. The needle crosses the full width of the column at a consistent angle, lays a single long stitch, and returns - then repeats just slightly offset, building a smooth column of parallel stitches that catches light.
Ideal use: letters in wordmarks, narrow column elements in logo marks, borders and outlines that need a defined edge, monogram strokes.
Width limit: roughly 8mm. Wider columns start to fail - the long unsupported stitches snag on contact, sag over time, and break easily. For anything wider, the digitizer splits the satin into multiple narrower columns or switches to fill stitch.
Density: typical 0.4mm stitch spacing. Adjusted up or down based on fabric: tighter on woven, looser on knit, much looser on fleece.
Fill Stitch (Tatami)

Fill stitch - also called tatami after the woven-mat texture it resembles - covers large solid areas with parallel rows of short stitches. Each row offsets the penetration points slightly so the surface looks patterned rather than ridged. The result is a stable, fabric-friendly solid color block that does not snag the way wide satin would.
Ideal use: the solid mark in a logo, large color blocks, background shapes, anything wider than the satin limit.
Patterns: standard tatami is the workhorse, but fill stitch has variants - parallel fill (single direction), random fill, and motif fill (patterned with shapes built into the fill). Different patterns suit different aesthetics.
Density: typical 0.5mm stitch spacing. Fill density runs slightly lower than satin because the surface is patterned rather than glossy-flat.
Run Stitch (Walking Stitch)

Run stitch is a single line of stitches - the needle walks along a path, penetrating at set intervals. It is the simplest and lowest-stitch-count of all the types. In the finished embroidery it shows up as a thin defined line, much narrower than a satin column.
Ideal use: outlines on logos, fine detail lines (whiskers, signature lines, fine borders), traveling between design elements without trimming the thread.
Stitch length: typically 3 to 4mm between needle penetrations. Shorter for tight curves, longer for straight runs.
Manual Stitch

Manual stitch is custom point-by-point digitizing where the digitizer places each stitch individually rather than letting software fill in a region. It is the most labor-intensive stitch type and the least common, used when the standard types cannot produce the needed effect.
Ideal use: custom decorative effects, unusual texture, very tight detail work that satin or fill cannot reproduce, controlled stitch direction in specific small areas. A skilled digitizer uses manual sparingly because of the time cost.
Specialty: 3D Puff
3D puff is a satin variant that sews over a layer of foam sandwiched between the fabric and the top stitches. The satin sews through and tacks down the foam, creating a raised dimensional letter or shape. The visible top stitch is still satin - the foam is the structural change.
Puff is most common on hat embroidery, where the dimensional effect reads well from a distance. It requires a denser top satin to fully cover the foam underneath, and a perimeter run stitch to clean up the foam edges after sewing.
Specialty: Applique
Applique combines a piece of fabric with embroidery stitches around its edges. The machine first stitches a placement outline, then pauses for the operator to lay a fabric patch over the outline. The machine then tacks the patch down with a tackdown stitch, and finally finishes the perimeter with satin or zigzag stitching.
Applique is useful for large color blocks where filling with thread would take 30,000-plus stitches but a fabric patch + perimeter stitching gets the same effect in 5,000 stitches. The fabric also adds a different texture from pure thread.
How a Digitizer Combines Them
A typical logo digitize uses all four core types together. The wordmark letters get satin. The logo mark - if it has a large solid area - gets fill. A border or outline gets run. Any unusual detail might get manual. The digitizer decides per element which type produces the cleanest result, then sequences everything so the machine runs efficiently.

FAQ
What is the most-used embroidery stitch type?
Satin stitch is the most visible and most-used stitch type in commercial embroidery. Almost every logo with text uses satin for the letters. Fill stitch dominates by stitch count on designs with large solid areas. Run stitch shows up on outlines and traveling between elements.
When does satin stop working?
Satin columns wider than roughly 8mm start to have problems: the long unsupported stitches snag, sag, or pull loose with wear. For anything wider, the digitizer either splits the satin into multiple narrower columns or switches to fill stitch.
Why is fill stitch sometimes called tatami?
Tatami is the patterned woven-mat appearance of the most common fill stitch style - parallel rows of short stitches with staggered penetration points. The pattern looks like the woven straw mats of the same name. Other fill patterns exist (parallel, random, motif), but tatami is the workhorse.
Does stitch type affect cost?
Indirectly - through stitch count. Satin packs more stitches per area than fill, so a satin-heavy design has higher stitch count and longer machine time. Run stitch uses the fewest stitches per unit length. The digitizer optimizes the mix to achieve the look at a reasonable count.
What is 3D puff?
3D puff embroidery uses a foam underlay sandwiched between fabric and the top satin stitches. The satin sews through and tacks down the foam, creating a raised dimensional letter or shape. Hat embroidery commonly uses puff for bold text. The base stitches for puff are still satin - the foam is the structural difference.
How is applique different from regular stitching?
Applique combines a fabric patch with embroidery stitches around its edges. The machine first stitches a placement outline, the operator lays a fabric patch into place, the machine tacks the patch down, and then finishes the perimeter with a satin or zigzag border. Applique reduces stitch count on large design areas and adds dimensional texture.
