Hi, I have taken over some clients from another therapist who has left for acrylic Infills, this has never been my string point but I'm really struggling with infilling them to get a really neat finish. It's taking the best part of 2 hours especially if they are being painted aswell. Do you have any helpful tips for me to become quicker and confident? Best files to use? Techniques? Also we use the edge tip and dip acrylic system.
