The sequence
- Placement line. A running stitch sewn on the stabilizer alone (tear-away or water-soluble, taut in the hoop) that draws the outline of the patch: it shows where to lay the twill.
- Machine stop. The machine stops; you lay the twill (cut larger than the patch, or as a strip) on the line, possibly with a dab of repositionable adhesive.
- Tack-down line. A running stitch, 1 mm inside the final edge, that holds the twill. On a multi-head, the operator lays the twill on every head during the stop.
- The design. Logo, arched text, optional background.
- The satin border. Sewn last, it covers the edge of the twill. Two methods: cut the twill flush with the tack-down before the border (an extra stop, a perfectly clean edge), or sew the border and then cut flush (faster, needs curved scissors or a laser).
The studio's patch tool generates this sequence with the stop in the right place; "Patch around" adds it to an existing design, with a classic shape or an outline that follows the design.
The border settings
- Width: 2.5 mm for a 5 cm patch, 3 mm for 8 cm, 3.5 mm above 10 cm. Too narrow, it does not cover the cut edge.
- Density: 0.35 to 0.40 mm, zigzag underlay. A border that is too dense lifts.
- Position: centred on the cut line, the outer half covering the edge.
- Corners: rounded (8 mm radius) if possible; sharp corners need mitred angles, which the studio makes automatically beyond 100°.
The fabric and the background
Polyester twill is the reference: stable, does not fray, comes in fifty colours. Choose it in the colour of the patch background so as not to embroider the background: that is half the stitches saved, a softer and cheaper patch. Felt suits soft patches for children; leather and faux leather need a denser border (0.30 mm) and a leather needle.
Cutting and attaching
With scissors: curved, 1 mm from the border, twill held taut. With a laser or a plotter: the studio exports the cut line as SVG or DXF, to be aligned with the embroidery. Heat-seal: embroider on twill that is already laminated with a heat-adhesive film, or apply the film after cutting with an iron (140 °C, 15 seconds). Hook-and-loop: sewn on the back, or twill with laminated hook-and-loop. Sew-on: nothing to do, the border serves as the guide.
Frequently asked questions
How many stitches for an 8 cm patch?
6,000 to 8,000 without an embroidered background, 12,000 to 16,000 with one. The background is expensive.
Which stabilizer?
Tear-away for the twill method (it comes away cleanly), water-soluble for a patch with no visible backing.
Can you make a patch on a domestic single-needle machine?
Yes: the sequence is the same, the machine stop becomes a manual stop between two colours. Count the thread changes.
