I was learning to do my own nails and the very first thing I chose was square nail extensions. And I wanted to do arch nails and it seemed like an easy idea to me, but I didn't take into account that I would be doing them myself and I had to spend about 8 hours on myself. It was a gel job and laying out the steps on the base and then the edge of the nail plate. My sister graduated from college school of beauty and told me that this kind of design is very difficult to do, especially the sawing of the nails after the material. But I was young and silly, I wore my nails for two days.
