Review on Versatile 100 PCS Multipurpose Sewing Clips in Assorted Colors - Ideal for Sewing, Crafts, Paperwork, and Hanging Small Items by Alicia Mayne

Love it so much. They are amazing. They're tricky to open at first, but once you open and close them a few times, it's all a breeze. They are very good but can leave small dents on some fabrics, cotton was fine but stains were fine on the upholstery. However, I didn't find that to be a problem, and these clips are still mostly placed on the seam allowances. The only downside is you can't use them to pin down the middle of a project, but you can hold a lot of fabric at once. Must buy more!
