My daughter is taking an nail course throu NSI this weekend, this is her second class and we are to show up to learn fills, cracks problem areas etc. I am her model. Problem is there is nothing wrong with my nails. growth very small only 2 weeks. so what are they going to do with them still fill and file down??? What are we to except. Silly question I know. I feel we are going to soon I quess. But this girl only takes 4 at a time and goes to other towns to teach plus runs her own business. And hands down is very good at what she does. She taught my daughter very well. Just not sure what they are going to do with me.
