Article in English: Now you are ready to begin! Take the piercing clamp and use it to clamp the skin of the navel and pull it out from the body slightly.  The entrance point you marked with the body ink should be centered in the bottom half of the clamp, while the exit point should be centered on the top half. Make sure to hold the clamp with your weaker hand, as you want the stronger, steadier one holding the needle. Take the sterilized, 14-gauge piercing needle. This needle has a hollow center, which will allow you to easily insert the belly button ring once you have pushed the needle through. Align the sharp end of the needle with the mark on the underside of the clamp. Take a deep breath, then with one fluid movement push the needle through the skin, making sure that the needle exits through the mark at the top of the clamp.  Never pierce from the top down. You need to be able to see where your needle is going and you can't do this if you're piercing downwards. The best way to pierce is while standing up, as this will give you the most mobility and allow you to see what you're doing. However, if you're concerned about fainting, pierce while lying down (not sitting!). Don't be concerned if the piercing bleeds a little -- this is totally normal. Just wipe away the blood with a clean q-tip dipped in saline solution. Place the end of the jewelry without the ball into the hollow needle (it should be virtually flush or slightly smaller than the needle) and push the needle out with the jewelry. DO NOT pull the needle out. You want to keep the contact between the needle and your navel ring for a smooth transition. The needle will fall off the end of the jewelry as it exits the skin so be prepared to catch it.  Refrain from pulling the needle out to soon, before the jewelry is fully through! Take the loose ball and screw it tightly onto the top of the belly button ring. Tah-dah! Your belly button is pierced! As soon as you've finished, wash your hands with antibacterial hand soap. Then take a cotton ball soaked in a saline solution...
