Hi, I have done a course in acrylic nails and iam using star nail products i dont think there the best but all i can afford at the moment, One problem that i have is that when i do zone 1 i find it hard to make zone 2 the same level if you understand. its like when ive finished ive got a big ridge where zone one has finished. I think maybe iam doing zone 1 too thick?? can someone give me some advise please any appriecated
