Use a thread with the same fiber content as your fabric. For instance, opt for cotton thread if you're sewing with cotton fabric.

Assess the Weight:

Thread weight is denoted by a number on the spool. Lower numbers indicate thicker threads, while higher numbers represent thinner threads. Match the thread weight to the fabric weight for balanced stitching.

Consider Color:

Choose a thread color that complements or matches your fabric. If you can't find an exact match, opt for a slightly darker shade rather than a lighter one.

Evaluate the Project's Purpose:

Select a sturdy thread-like polyester or nylon if your project requires strength and durability. Silk or metallic threads may be more suitable for delicate fabrics and decorative stitching.

5. Needle-Related Thread Breakage

Needle-related thread breakage occurs when issues with the sewing machine needle cause the thread to snap during sewing. The needle is critical in guiding the thread through the fabric and forming stitches. A damaged, bent, or dull needle can cause the thread to fray, weaken, and eventually break, leading to frustrating interruptions in the sewing process.
