i suggest bobby pins over paper clips, cause paper clips bend really easy.
you might have to shave off the tip of the bobby pin depending on brand.
but i have a video on bobby pin/paper clip picking

i made that like 6 months ago, and it kinda sux. my new ones are much better, but thats the only one with paper clips.
hope that helps :]
