I wouldn't know how to quilt without them. I hate the little sewing pins we used when I was making clothing and other crafty things. I've been using them for over 16 years now and am faithful to them. I use the curve pins to pin my quilt when quilting it and remove them as I sew a section of quilt. I use these pins for everything I sew now except may fine applique which I don't do that much. My hands are too stiff for that. I guess its a matter of getting used to using them. When pinning a seam, I put it at an angle catching both seam allowances in the pin. Works well for me.
