Skipped Stitches
Skipped stitches, characterized by the needle failing to properly interlock the thread within the fabric, are a common issue when using an incorrectly sized needle. A needle that is too small struggles to penetrate dense denim, resulting in missed loops and a weakened seam. This is particularly problematic in high-stress areas like seams or pockets. For example, a size 11/75 needle used on heavyweight denim is likely to result in skipped stitches, compromising the garment’s structural integrity.
-
Thread Breakage
Thread breakage occurs when the thread is subjected to excessive friction or tension. Using a needle that is too small for the chosen thread, or for the denim’s weight, increases friction as the thread passes through the needle eye and fabric. This heightened friction can weaken and ultimately break the thread, interrupting the sewing process and creating uneven seams. For instance, using a lightweight thread with a size 18/110 needle can cause the thread to break repeatedly, necessitating frequent re-threading and potentially damaging the fabric.
-
Seam Puckering
Seam puckering, characterized by a wavy or uneven seam line, can result from an imbalance between needle size, thread tension, and fabric weight. A needle that is too large for the denim can displace the fabric fibers, causing them to bunch up around the stitches and creating a puckered appearance. This is particularly noticeable in lightweight denim. For example, using a size 16/100 needle on lightweight stretch denim may result in noticeable seam puckering, diminishing the garment’s aesthetic appeal.
-
Uneven Stitch Length
Uneven stitch length, where the stitches vary in size along the seam, can indicate an incompatibility between the needle size and the fabric. A needle that is too large can create large, irregular stitches, while a needle that is too small can lead to short, tight stitches. This inconsistency compromises the seam’s strength and appearance. Using a size 14/90 needle intended for medium-weight denim on very heavyweight denim may result in short, uneven stitches that weaken the seam.
These stitch quality issues underscore the critical relationship between needle size and successful denim sewing. Selecting the appropriate needle size, based on the denim’s weight and the chosen thread, ensures even stitch formation, prevents thread breakage and skipped stitches, and minimizes seam puckering.
