Wonder Clips are a great alternative to pins, especially when working with heavy weight fabrics, piles, and vinyls. The clips can hold layered sections of sewing projects such as handle connectors to handbags and piping without distortion. Wonder Clips can also hold quilt binding while sewing. These clips have a wide opening for holding multiple layers of fabric. They won't damage or distort the fabric.
The clip base is flat for easy feeding to presser foot with 1/4" and 1/2" seam allowance markings on the base. I like to use Wonder Clips for holding pleats on skirts, curtains, and the sleeves on men's shirts. Wonder Clips have a firm grip on the fabric and they are excellent when used on quilting projects. Wonder clips do not damage or distort the fabric. They should be a necessary tool of anyone's sewing room. I use Wonder Clips frequently when I sew formal dresses so that the formal stays perfect without any flaws on it from sewing the formal.
Wonder clips come in different sizes and quantities in a package. It depends on your sewing project on what size of wonder clip you will need. A heavier fabric or multiple layers of fabric will need a larger wonder clip while a less thicker fabric will require a smaller wonder clip. The smaller wonder clips are handy in holding small bows in place while you are hand sewing them in place or gluing them into place. I use them for holding trim such as lace in place while I sew. They are good for holding craft projects in place after gluing until the glue is dried. You can find some Clover Wonder Clips here for your sewing needs.
