When sourcing crochet bags, the price is primarily driven by material composition, complexity of the stitch pattern, and labor hours. For premium markets, prioritize 100% mercerized cotton or eco-friendly raffia, which offer better structural integrity and colorfastness than cheap acrylic. Ensure the lining is made of high-density polyester or cotton canvas to prevent sagging. A key quality indicator is the uniformity of tension; inconsistent stitches often signal low-quality manual production or lack of standardized QC.
