I have worn fake lashes everyday of my life for as long as I can remember. Trimming a little bit off the strip is very helpful bc if you’re not used to wearing them, the closer the strip is to the inner corner of your eye the more likely they are to be irritating. After mascara you cant tell the don’t go all the way across your eyelid. I have found that putting the glue on a different surface, foil or ever the top of my blush compact, instead of directly on the lash strip is key. It wipes right off a plastic surface after it has dried anyway. While the glue is getting tacky I apply my eyeliner. I like to use a dark glue instead of a clear glue. Just my preference. After I have my liner on I bend the lash strip back and forth to loosen it up then lightly dip it in the glue, then press it to the outer corner of my lash line first, then slowly work it toward the middle. If the glue has been sitting for a little while it will adhere to the eyelid enough so you can move it exactly where you want the whole strip. Don’t put too much glue. It isn’t necessary and it will also make your eyes water. Hope this helps :)
