Measure your lashes against your natural lash line. Trim the excess lashes carefully, one lash at a time. Curl and apply mascara to your natural eyelashes. Apply a thin line of lash glue to the lash band and wait 30 seconds for the glue to become tacky. Place the lashes as close to your lash line as possible. Use your fingers to press down on both corners of your lid to secure lashes.
