Hair Replacement

I can not find the hair clip! but if I wanted I could just use bobby pins, if so, how would I do that? they should sell these clips, where extensions have been sold and I tried to change the clip with hairpins, and all renewals does not just fall, not to the place I've tried Bobbi pins. they are not very good, but if you really, I used an X could be run from the top and the other would be rotated on the bottom does. It is not a good idea to use bobby pins. Hair Extensions can be easily removed by using it. Perhaps the French clip or ponytail is better
