First, check the fit by holding the lash strip against your eyelid (along your natural lash line) and trim down if necessary. 

 Next, apply lash glue (not included) to the faux lashes along the cotton strip and wait for the glue to dry (to a tacky like finish) before applying them to your natural lashes. Take care to place the strip as close as possible to your natural lash line. Hold still until the strip is secure and sits comfortably.
