I am currently in school learning acrylic nails. I am having a hard time with the "c" curve. I've watched a few videos on YouTube where the nail tech used a c curve pincher but there was no real demonstration on the correct way to put it on. I asked my teacher and she said she doesn't believe in them and that it is "cheating". I tried it at home and just ended up squishing my acrylic and making a mess. Does anyone have any advice or tips I could try? TIA
