A lock stitch is created by interlocking two threads—a top thread and a bobbin thread. The top thread is fed through the needle and forms a stitch on the front of the fabric. The bobbin thread, located in a lower compartment of the machine, loops up to meet the top thread, forming a secure stitch that is often used for a wide array of sewing applications. This type of stitch is characterized by its tightness and durability, making it suitable for sewing heavier materials such as denim and canvas, while also being gentle enough for lighter fabrics.
Lightweight and portable, handheld sewing machines allow for easy maneuverability and can be stored in compact spaces. They are particularly beneficial for those who may have limited workspaces or need to transport their sewing tools frequently.

A shorter stitch length for lighter fabrics can provide a more delicate seam that blends well with the fabric’s natural drape. Conversely, a longer stitch suits heavier materials, providing stronger holds. Adjusting stitch width is particularly crucial when creating decorative stitches or buttonholes. By tailoring these settings, one can achieve a professional finish, reducing skipped stitches or fabric bunching risks.
