I absolutely love them! I'm using them on my current project where I'm using connecting sashing for my QAYG queen size quilt. They keep the material neatly while I stitch, also use them to hold my quilting stencil in place. Haven't used them for binding yet, but that is coming next. I bought two boxes of 50 and so far I' very very pleased. Can't say that about all the gadgets out there.
