This set includes triangular tailor’s chalk and sewing clips. The chalk is made from compressed gypsum, allowing for smooth marking on cotton, denim, linen, and other common fabrics; marks can be removed with water or alcohol, making it ideal for cutting and layout work. The clips feature injection-molded plastic bodies and metal springs that use tension to hold fabric securely. Capable of holding multiple layers of fabric to prevent shifting during sewing, they are perfect for quilting, appliqué, and garment making. Used together, the chalk and clips cover the essential steps of the sewing process, from marking to alignment. Regarding manufacturing, the chalk is formed via mold pressing, the clip body is injection-molded, and the assembled spring undergoes a tension test. It is suitable for crafting projects such as quilting, garment repair, and home décor.
