How do you put on false lashes??? 😩

I’ve been trying so hard and they never apply correctly or look right. I have lots of trouble with the inner and outer corners not sticking. I’ve watched tons of tutorials and have no idea what I’m doing wrong! I know it takes time getting used to but it’s literally been months since I’ve been trying to get it right. I use Ardell Demi wispies, which have a thin band so it’s supposed to be easier. Tips please!!
