Fill Stitch

Definition and Overview

Fill stitch is an embroidery technique that densely places stitches running in a consistent direction, filling in the surface of text or patterns. Because the stitches resemble the weave of tatami mats, it is also called tatami stitching, and it is widely used when creating machine embroidery data.

Even among stitches that fill a surface, it differs from satin stitch, which packs stitches closely along the outline. Fill stitch is suitable for relatively large areas, and the direction and length of the stitches can be used to adjust gloss, shading, and expression.

Its Role in Product Development

Fill stitch is one type of secondary processing that adds a design to fabric before cutting, after cutting, or on sewn products. In general, the submitted data is converted into data for an embroidery machine, and production moves to full-scale manufacturing after conditions are checked with a test run.

At the design stage, determine the embroidery area, number of colors, and the texture you want to express. Because the finish changes depending on the fabric's stretch, thickness, pile, and weave density, it is important to align specifications with the embroidery provider after the material is decided.

• Embroidery position and the up-down and left-right orientation of the design
• Color and number of embroidery threads to use
• Stitch direction, density, and overlap
• Type of stabilizer and removal method
• Whether it is pre-sewing processing or post-production processing

How to Proceed and Practical Points

When placing an order, provide a design with the finished dimensions clearly stated, placement instructions, color instructions, and the fabric or fabric information. An image alone makes it difficult to judge the stitch structure, so also confirm the adjustment policy during embroidery data creation, such as whether fine lines should be omitted or changed to another stitch.

Before full production, run a test sew under conditions close to the actual fabric to be used. In particular, with large solid areas, the embroidery can cause shrinkage or waviness in the fabric, and stretch fabrics may deform, so check the hooping, stabilizer, and sewing order as well.

Quality and Ordering Considerations

When checking quality, inspect the outline of the design, missing stitches, thread breaks, and irregularities in color changes, as well as puckering around the embroidery. Because fill stitch places stitches across the entire area, if the density is too high, the fabric may become stiff or shrink.

Lowering the embroidery density makes it easier to achieve a lighter, softer feel, but the base fabric may become more visible and the texture may look rough. In addition to the desired appearance, share pass/fail criteria using a prototype, including comfort when worn, changes after washing, and ease of handling during sewing.

Differences from Similar Terms

Satin stitch is a stitch that fills a narrow area with dense stitches and is suited to text, lines, and details with clear outlines. By contrast, fill stitch runs stitches continuously, making it suitable for filling larger areas.

Embroidery punching refers to the work of converting a design into data that an embroidery machine can sew. Fill stitch is one type of sewing method selected within that data. Also, saori embroidery is a three-dimensional technique that layers thread in loops, and its appearance differs from fill stitch, which is based on flat surface filling.
