Okay then you have to know how, or rather be patient and careful to successfully is the solution. I can assure you that I had no knowledge before starting Nail Art and order Striping Tape. I just wanted to have beautiful hands so beautiful nails, I had time since my accident and want to try. So I placed my order and when I received it I threw myself into the water !! Frankly my first were not so great, I wanted to go too fast (yeah, everything immediately me). So I took my time between each finger and I put my top coat to protect my bands and finally the result the results have amazed me !! I frankly recommend but do not think you can keep doing great work in the house: it is still fragile. Remember the top coat and gloves if you have to rub the car !!
