Love the clips! Beware-I bought a batch on Amaz** that hurt my arthritic thumb to use. I bought them because the neon colors were pretty. I have to weed them out of my stash by just tossing the ones that won't open easily.

I have the original wonder clips but also the ones from Amazon and I don't see a difference in them.

I have never used bobby pins before, I'm sure that works just perfectly. I do use binder clips, that are used for large ounces of paper, they work great and come in lots of different sizes

I love the wonder clips also.

I sewed three Hogwarts robes out of heavy gabardine for Halloween. The fabric was so thick that my pins had trouble holding it where seams crossed. Enter the clips! It made sewing the heavy fabric so much easier. I also use them for sewing masks; they hold the fabric where it should be whether shaped seams or pleats.
