These sewing clips feature letter and number markings, allowing for the categorization and labeling of fabric pieces in quilting and craft projects. Made via plastic injection molding, the clips display clear characters that are easily legible from a distance. They utilize metal springs to provide the tension needed to hold fabric securely. The clip surface features a non-slip texture for a stable grip, making them suitable for holding thick or multi-layered fabrics. Ideal for quilting, appliqué, garment making, and crafting, these clips help users organize design sections by row or column. Production involves mold-based injection molding for the body, character formation via molding or printing, and post-assembly spring testing. Lightweight and compact, they fit easily into storage boxes or craft bags and are suitable for users of all skill levels.
