Hi all! Just been practising my smile and have a few problems. I find my smiles looking nice and neat before i apply the pink. Actually they even look neat until I begin to file. Then having finished up I'm always a little dissapointed with them, finding there just not crisp, or half of it is and then it trails off. I dunno. I know its to do with creating the little cove thingy (wall) so the pink sits nicely in it but I'm going wrong somewhere. I was taught to clean out the smile lines, does any one else do this? Form the smiles, then use the end point of the brush to clean it out. So place in the centre of the smile under the ledge wall thingy and swipe it from the centre and up to the right and then again from the centre up to the left. Is this common practise or could this be part of my problem? I have read the tutorial on here and noticed smile lines were creating my pushing acrylic upwards not touching the smile line at all and there was no mention of cleaning out. I also tried this and it was a little difficult. Any advice would be great. Thanks.
