These large quilting clips are manufactured using plastic injection molding and metal springs, relying on spring tension to securely hold fabric. With a wide opening angle, they are perfect for securing thick fabrics, quilt sandwiches, and binding materials, and are also useful for machine sewing, bag making, and home organization tasks. The sturdy clip body is designed for daily use. Available in multiple colors, the clips facilitate categorization by fabric layer count or project type, helping users organize multiple tasks. They are suitable for quilting, binding, hemming, and crafting, and can also serve as paper clips. Manufactured via injection molding, the clips undergo spring tension testing after assembly. Lightweight and easy to store in a box or craft bag, they are a staple tool for sewing and quilting.
