I love the small Clover Wonder Clips. I use them instead of a pin when I can. My DD bought me a tub of another brand and they work fine but I can tell a difference from the Clover brand in the way the clips hold the fabric and spring strength. If you haven't used the Clover brand you won't know the difference though. Did you know there are fake Clover products? Be careful to get what you pay for. Here is the difference in the real and the fake:
