Here is a professional makeup artist's tutorial on sticking false eyelashes:

Preparation
Select False Eyelashes: Choose false eyelashes that suit your eye shape and the style of your makeup. For example, wispy lashes are suitable for those with small eyelids or those who want to make their eyes appear larger. Longer lashes at the outer corners can create a cat-eye effect.
Gather Tools: You'll need false eyelashes, eyelash glue, tweezers, an eyelash curler, eyeliner, and mascara.
Application Steps
Prepare the Eyes: Curl your natural eyelashes with an eyelash curler to make the false eyelashes blend in better with your natural lashes.
Trim the False Eyelashes: Take out the false eyelashes and hold them against your lash line to check the length. Use small scissors to trim off the excess, and make the cut at a slant for a more natural look.
Apply Eyelash Glue: Squeeze an appropriate amount of eyelash glue onto the root of the false eyelashes. Use a thin layer of glue to avoid getting it in your eyes. If using individual lashes or clusters, you can put a dime-sized amount of glue on a palette and dip the base of the lash into it.
Wait for the Glue to Dry Slightly: Let the glue dry for about 10-30 seconds until it becomes tacky.
Attach the False Eyelashes: Look down at a mirror placed at a nearly perpendicular angle to your face. Use tweezers to hold the false eyelashes and first attach the middle part to the root of your natural eyelashes. Then, gently press the eyelash roots at the inner and outer corners of the eyes to make them adhere firmly.
Adjust the False Eyelashes: After attaching the false eyelashes, adjust their angle and position to make them fit your eye shape better and blend seamlessly with your natural lashes.
Blend with Eyeliner and Mascara: Use eyeliner to draw a line along the root of the false eyelashes to cover the lash band. Then apply mascara to blend your natural lashes with the false lashes
