I moved away from pins to clips last year. Too many pins would bend or not be sharp enough to go through several layers of fabric. I received a small package of these pins in a subscription box and found them to be perfect for holding multiple layers together. Currently working on "Wild Blue Yonder" for my grandson's first birthday and the entire pattern for each plane can be held by one pin. They are long and very sharp - I'll continue to use them when I can't use clips.
