If you’re having issues with your product quality, it is easy to blame the last set of hands who touched it. However, the last person who touched it is rarely the cause of the problem. If you trace back the steps and hands that garment went through, it is often an upstream problem that trickled down and compounded to become the issue you are seeing.
If you are noticing the sewing is bad, take a look at the quality of the cutting, patternmaking, or base design specs that came before it. The end product is only as good as all the inputs and processes that created it. Said another way, even the most skillful sewer cannot fix problems with the cut pieces that were given to them and the most precise cutter can’t compensate for a poorly made pattern. There certainly can be quality issues with sewing as well, but don’t assume that sewing is always the root of the issue.
This is not to say that each step should pass the blame for any quality issues to the person before them. In fact, I’m kind of saying the opposite. Each person can take responsibility for how the quality of their work affects the work of the person who touches the product after them. In an ideal, collaborative environment, everyone at any step in the process has the opportunity to catch and bring up any problems or potential concerns they see and together find how to avoid the issue in future. This is what a good pre-production sample test allows.
The design and product development steps have the most impact on the quality of the final product. A thoughtfully designed garment can be smoothly produced with consistent quality.
