Just to let you know.
Your lobes are MUCH different from your helix.
There is much more danger involved with doing any cartilage piercing.
You could really mess up your ear, and get an infection.
Just because you did not get one before even though you did your own does not mean you are not still prone to infections and CAN get one.
Using a sewing needle is a stupid idea, and using a earring to pierce it with is as well.
For one a sewing needle is not sharp enough to actually pierce your cartilage, and it will leave no room for the earring that you stick in.
And you really think that you want to sit there a force an earring into your ear, and use that to pierce what an idiot.
You NEED a proper piercing needle to do such a piercing.
And you do not have anything to sterilize your things.
Sorry to say, BUT USE YOUR BRAIN AND GET IT DONE PROFESSIONALLY!!!!!!!
And personally I don't care how much you don't want people to 'rant' at you about going and getting it done the right way, you knew you were going to get it so why even ask the question.
My question to you is why can you not go get it done by a professional?
