Use satin stitch for narrow, glossy shapes, fill stitch for broad areas and running stitch for fine lines and outlines. Choose for each part of the design at its finished embroidery size; one logo can use all three.
Which stitch fits each shape?
Design element | Practical starting choice |
|---|---|
Fine outline or line drawing | Running stitch follows a single path. |
Narrow border or lettering stroke | Satin spans the column to create a smooth, glossy surface. |
Broad solid shape or background | Tatami fill covers the area with rows of shorter stitches. |
These are starting points rather than fixed rules. Hatch’s stitch glossary explains the basic structures and their uses.
Running stitch: fine lines and detail
Running stitch places consecutive stitches along a line, much like a pencil tracing a path. It suits delicate outlines and linear details. Stitch length can vary to follow tight curves more closely. See the Hatch definition of running stitch.
Small lettering needs more judgment. A purpose-designed running-stitch font can work where a satin column is unsuitable, but changing every tiny letter to a running outline is not a universal fix. Hatch provides both running-stitch fonts and small satin fonts, each with recommended size limits. Follow the selected font’s guidance and check the actual sewn result. Hatch’s font guide explains these distinctions.
Satin stitch: smooth borders and lettering
Satin stitches cross a narrow shape from side to side. With few intermediate needle penetrations interrupting the surface, they produce the familiar glossy appearance used for borders, script lettering and other column-shaped details.
Pay attention to the width of the individual stroke, not just the overall size of the logo or letter. A large letter with narrow strokes may still suit satin; a smaller solid shape may need fill.
There is no universal half-inch satin limit. Machines have maximum stitch lengths, and software can split long satin stitches into shorter segments. Those extra penetrations change the surface appearance. For broad areas, consider tatami fill or divide the artwork into suitable sections. Wilcom’s satin documentation explains narrow-column applications and automatic splitting.
Fill stitch: coverage for larger areas
In this comparison, “fill” means tatami fill: rows of running stitches covering a shape. It is useful for large or irregular areas that would require long stitches if sewn entirely in satin. Wilcom’s tatami guide describes these applications.
Stitch direction and pattern affect the texture. However, fill does not automatically mean a low stitch count. Enlarging a filled design can increase its stitch count substantially, so a jacket-back version deserves a fresh review even if a smaller chest version worked well. Wilcom’s scaling examples show why embroidery does not scale like a printed image.
Choose at the size and on the fabric you will use
Start with the finished dimensions. For buyers and decorators working across the US, Canada and UK, specify units clearly—for example, 3 inches wide (76.2 mm)—and identify the garment, fabric and placement.
Then assess each element separately. An illustrative leaf design might use tatami for its broad body, satin for a substantial border and running stitch for fine veins. This gives each part a stitch structure suited to its shape.
Fabric also affects the settings. Stitch spacing may need to change between fabrics and objects, while crowded stitches around tight curves can cause thread breaks. Choosing a stitch type is therefore only part of preparing the design. Wilcom’s stitch-spacing guidance explains these relationships.
Before a production order, ask your embroiderer to sew a sample at the intended size on matching material. Inspect the lettering, edge alignment, coverage and feel. If you need help preparing the file, explore DigitEMB’s embroidery digitizing service and provide the artwork, finished dimensions, garment details and required machine format.
Frequently asked questions
Can one logo combine satin, fill and running stitches?
Yes. Choose stitch types by element: satin for narrow columns, tatami for broad shapes and running stitch for fine paths. The whole design does not need one stitch type.
Is running stitch always best for very small text?
No. Some small lettering uses specially digitized satin columns; other lettering uses running-stitch fonts. Use the font’s recommended size range and confirm legibility in a sewn sample.
Should wide satin always become fill?
Tatami is a useful starting choice for broad coverage, but splitting satin or dividing a shape may also be appropriate. Review the desired finish, machine limits and sample before deciding.
