Our best tip, go SLOW! Remember you can always cut more off, but you can't put more back on. We recommend you use a smaller pair of scissors to cut your lace for precision and accuracy. 1. Begin by using some clips and clipping all the hair away from the lace. This prevents you from accidentally cutting any hair.2. Slowly trim around the hairline, starting at one ear and finishing at the other. 3. Aim to leave about 1/4 - 1/2 inch of lace beyond  the hairline. If you cut directly to the hairline, you may find you have issues with the lace sitting flat against your forehead. 4. Once you've made your cuts, try the wig on and see how it looks. From there, you can choose to cut more if necessary.
