Here is a video on applying false lashes for those who haven't mastered it yet.
When I use false lashes, I grab the lash and put a thin line of lash glue on the part that attaches to the lid. I take both sides of the lashes and curl them and blow on the glue so it becomes tacky. I then place the lash on. I cover it with my Mac Blacktrack gel liner. I am no pro so any advice I give may not work for everyone. Hope you enjoy!
