    Fill Stitches (Tatami) Explained

    Fill stitches cover large areas with texture and direction. Here's how they work and how to use them well.

    A fill stitch — often called tatami — covers a large area with rows of stitches. Direction, density, and pattern all affect how the finished fill looks and feels.

    Working With Fill Stitches

    • Fills cover areas too large for a single satin stitch.
    • Stitch direction (angle) changes how light reflects off the fill.
    • Density controls how solid and heavy the fill looks.
    • Underlay beneath a fill stops it from sinking into the fabric.
    • Patterned fills add texture for a decorative effect.

    How to Get It Right

    1. 1Keep density moderate so fills stay soft and don't pucker.
    2. 2Vary the fill angle between adjacent areas for contrast.
    3. 3Always include underlay under large fills.
    4. 4Lower density on lightweight fabrics.
    5. 5Use the preview to check coverage before stitching.

    Density Is the Dial

    If a fill looks heavy and stiff or causes puckering, reduce the density. Lighter fills are softer and lie flatter.
