Selecting the correct needle size for sewing denim is crucial for project success. Generally, a needle size within the range of 90/14 to 110/18 is recommended for typical denim fabric. Heavier denim, such as that used in workwear, might require a larger needle, such as a 100/16 or 110/18. Lightweight denim, conversely, may be effectively sewn with a smaller needle, like a 90/14. The needle size designation refers to the needle’s diameter (the first number, with higher numbers indicating thicker needles) and the American sizing equivalent (the second number). Choosing an appropriate size helps prevent broken needles, skipped stitches, and damaged fabric.
Appropriate needle selection ensures the integrity of the stitching and the overall quality of the finished garment. A needle that is too small can break under the stress of the thick fabric, potentially damaging the sewing machine. Conversely, a needle that is too large can leave visible holes and weaken the fabric’s weave. Historically, the development of specialized needles for heavier fabrics like denim was a significant advancement in garment construction, enabling the efficient creation of durable and long-lasting clothing.
