Underlay Stitch For Embroidery: Mastering The Basics

Embroidery is a timeless art that combines creativity and precision to produce stunning designs. One of the key techniques that every embroiderer must master is the underlay stitch. This foundational stitch sets the stage for the final embroidery, ensuring that the design is well-supported and has a polished appearance. In this article, we will delve into the essentials of underlay stitches, their importance, and how to effectively incorporate them into your projects. Along the way, we will also explore the relevance of underlay stitches in digitizing processes, particularly in the context of the USA and logo digitizing.

Understanding Underlay Stitches

What is an Underlay Stitch?

An underlay stitch is a preliminary layer of stitching that is applied before the final stitches in an embroidery design. It serves as a foundation that stabilizes the fabric, minimizes puckering, and enhances the overall quality of the embroidery. Underlay stitches are typically hidden beneath the top stitching, providing support without being visible in the finished design.

Types of Underlay Stitches

There are several types of underlay stitches, each serving a specific purpose. The most common types include:

  1. Edge Run Underlay: This stitch runs along the edges of the design, providing a clean and crisp outline. It is particularly useful for preventing the fabric from shifting and ensuring that the edges of the design remain sharp.
  2. Zigzag Underlay: This stitch creates a zigzag pattern underneath the top stitching. It is ideal for providing additional support to large, open areas of the design and is commonly used in satin stitches.
  3. Tatami Underlay: Also known as a fill stitch, the tatami underlay covers a larger area with a series of parallel lines. It is used to stabilize the fabric in larger designs and is particularly effective for filling in dense areas.
  4. Center Run Underlay: This stitch runs down the center of the design elements, providing support for narrow columns and small details. It is often used in conjunction with other underlay stitches to ensure comprehensive stabilization.

Importance of Underlay Stitches

Underlay stitches play a crucial role in the success of an embroidery project. Their benefits include:

  • Fabric Stabilization: By providing a stable foundation, underlay stitches prevent the fabric from shifting or puckering during the embroidery process.
  • Enhanced Design Quality: Underlay stitches create a smooth surface for the top stitching, resulting in a cleaner and more professional-looking finished product.
  • Longevity: By minimizing the wear and tear on the fabric, underlay stitches help to extend the life of the embroidery.
  • Improved Coverage: Underlay stitches ensure that the top stitches have a consistent and even appearance, especially in designs with varying stitch densities.

Incorporating Underlay Stitches in Digitizing

The Role of Digitizing in Embroidery

Digitizing is the process of converting a design or image into a digital embroidery file that can be read by an embroidery machine. This involves creating a series of stitch instructions that guide the machine in reproducing the design on fabric. In the context of the USA, digitizing has become a critical aspect of the embroidery industry, with many businesses specializing in logo digitizing for branding and marketing purposes.

Underlay Stitches in Digitizing

Incorporating underlay stitches into the digitizing process is essential for achieving high-quality embroidery results. Here are some key considerations:

  1. Design Analysis: Before digitizing, it is important to analyze the design and determine the appropriate type and placement of underlay stitches. This involves considering factors such as the fabric type, stitch density, and design elements.
  2. Software Capabilities: Modern digitizing software offers a range of tools and features for creating underlay stitches. These tools allow digitizers to customize the type, density, and direction of underlay stitches to suit the specific requirements of the design.
  3. Balancing Underlay and Top Stitches: Achieving the right balance between underlay and top stitches is crucial. Too much underlay can result in a bulky and stiff design, while too little can compromise the stability and appearance of the embroidery.
  4. Testing and Adjustment: After digitizing the design, it is important to conduct test runs on the embroidery machine. This allows for the identification and adjustment of any issues related to underlay stitches, ensuring optimal results.

Best Practices for Underlay Stitches in Logo Digitizing

Logo digitizing presents unique challenges, as logos often contain intricate details and require precise reproduction. Here are some best practices for incorporating underlay stitches in logo digitizing:

  1. Consistent Edge Run: Ensure that edge run underlay stitches are used consistently around the perimeter of the logo elements. This helps to maintain clean and defined edges.
  2. Appropriate Density: Adjust the density of underlay stitches based on the fabric type and design complexity. Heavier fabrics may require denser underlay stitches for added support.
  3. Layering Techniques: Utilize layering techniques to create a smooth transition between different design elements. This involves carefully planning the sequence and direction of underlay stitches.
  4. Minimize Bulk: Avoid excessive underlay stitches in areas where the top stitching will be dense. This helps to prevent the design from becoming overly thick and rigid.

Practical Tips for Mastering Underlay Stitches

Fabric Considerations

The type of fabric used in an embroidery project can significantly impact the effectiveness of underlay stitches. Here are some fabric-specific tips:

  1. Lightweight Fabrics: For lightweight fabrics such as silk or organza, use lighter underlay stitches to prevent distortion. Edge run and zigzag underlays are often suitable for these fabrics.
  2. Heavyweight Fabrics: For heavyweight fabrics such as denim or canvas, denser underlay stitches are necessary to provide adequate support. Tatami underlays can be particularly effective in these cases.
  3. Stretch Fabrics: Stretch fabrics such as jersey or spandex require underlay stitches that accommodate the fabric’s elasticity. A combination of zigzag and center run underlays can help to stabilize the fabric while allowing for stretch.

Stitch Density and Length

The density and length of underlay stitches should be adjusted based on the design and fabric type. Here are some general guidelines:

  1. Stitch Density: For dense designs, increase the density of underlay stitches to provide additional support. Conversely, for lighter designs, reduce the density to prevent bulk.
  2. Stitch Length: Longer underlay stitches are suitable for larger areas, while shorter stitches are ideal for intricate details. Adjust the stitch length accordingly to achieve the desired effect.

Machine Settings and Maintenance

Proper machine settings and maintenance are essential for achieving optimal results with underlay stitches. Consider the following tips:

  1. Tension Settings: Ensure that the machine’s tension settings are properly adjusted to prevent thread breakage and ensure smooth stitching.
  2. Needle Selection: Use the appropriate needle size and type for the fabric and thread being used. This helps to achieve clean and precise underlay stitches.
  3. Regular Maintenance: Keep the embroidery machine clean and well-maintained to prevent issues such as thread jams and uneven stitching.


Mastering the basics of underlay stitches is essential for achieving high-quality embroidery. By understanding the different types of underlay stitches, their importance, and how to incorporate them into the digitizing process, embroiderers can create stunning designs with precision and professionalism. Whether you are working on intricate logos or large-scale designs, the right underlay stitches can make all the difference in the final outcome. Embrace the power of underlay stitches and elevate your embroidery projects to new heights.
