Underlay Stitch For Embroidery And Digitizing

In general, underlay stitches are the most unnoticed arteries of embroidery, which add subtlety to the basis of the stitched design and help the upper stitches stand out. For those working on detailed small graphics or large stripes, it is impossible to avoid coming across underlay and baste stitches, which are essential for creating high-quality embroidery digitizing.

This Guide Covers:

• What are underlay stitches?

• Why underlay stitches are essential.

• How to properly apply underlay stitches in embroidery digitizing.

What Are Underlay Stitches?

Back stitches are laid before sewing embroidered ones on the material to create a settling base on which the embroidery will rest. They support the fabric and anchor the design firmly while also preparing the area for the final sewing.

Types of Underlay Stitches

• Center Walk: Passes vertically through the design element. It is fast and perfect for lines and stripe motifs.

• Edge Walk: A straight stitch drawn parallel to the edges of the design component.

• Zigzag Underlay: A stitch with a zigzag formation, giving a broader base than the stitch just described.

• Tatami (or Fill) Underlay: A grid pattern used under larger fill areas.

Why Underlay Stitches Are Significant

Underlay stitches are vital to determining the success of an embroidery project.

Here’s Why They’re Essential:

• Stabilization: Prevents fabric movement during embroidery, reducing wrinkles.

• Support: Keeps top stitches from sinking into the fabric.

• Shape Definition: Establishes the edges of the designs for sharpness and detail.

• Enhanced Appearance: Lifts top stitches, adding depth and surface quality to the embroidery.

When to Use Underlay Stitches

Underlay stitches are not always required for every design, but they are essential in certain situations:

• Dense Fabrics: Prevents distortion and maintains contrast on thick fabrics.

• Large Designs: Provides the necessary support to keep fabric stable.

• Loose Weave Fabrics: Helps reduce distortion on delicate fabrics like knits.

• Complex Designs: Essential for maintaining clarity in intricate patterns.

How to Choose the Right Underlay Stitch

When selecting the proper type of underlay stitch, consider factors like fabric type, design size, stitch density, and desired appearance.

• Fabric Type: Soft and pliable fabrics need more support, making edge walk and zigzag underlays ideal.

• Design Complexity: Simple designs work well with a center walk underlay, while complex ones may require multiple underlay types.

• Stitch Density: High-density designs benefit from tatami underlay, whereas low-density designs may use zigzag underlay.

Underlay Stitch Techniques in Digitizing

In embroidery digitizing, underlay stitches are as valuable as top stitches. Here’s how to incorporate them effectively:

1. Plan Ahead

Match the underlay stitch type with the fabric and design. Underlay stitches should be a priority in the digitizing process.

2. Layering

Use multiple underlay stitches to create a robust foundation. For example, combining edge walk and zigzag underlay can add extra support.

3. Adjust Settings

Most embroidery software allows adjustments in density, length, and type of underlay stitch. Modify these settings according to project needs.

4. Test Samples

Always test your design on fabric samples before finalizing. This helps identify problem areas and refine the outcome.

5. Optimize for Efficiency

Although underlay stitches are crucial, they increase stitch count. Use the most suitable underlay type to achieve the desired result without excessive stitching.
