Hi, I recently got myself trained in how to apply Minx nails and have been practicing since then to perfect my technique before I add to my treatment menu, however, I am having difficulty getting a neat finish to the edge of the Minx wrap when I file it off. I find I have to file quite hard with the glass file to get the excess wrap to come away which always leaves a ragged edge. The tutor told us to smooth this down with a rubber hoof which I've tried but it just doesn't seem to work. Any advice or tips on how to overcome this problem would be most welcome................. Thanks!
