Watch the video on her page for a lot of great tips http://www.myspace.com/triciasawyer.
Like everyone said, it's just time and practice. Make sure you are letting the glue get tacky enough so that the lashes will grab when you first lay them down and you can move them and adjust them without pulling them off when you move your hand away. Also, I apply just a little bit more glue on the inner and outter corners where they tend to lift off. I just make sure that area is covered on all sides.
I've had the hardest time with putting lashes on myself for so long and now it's finally starting to come easy on the first shot. It just takes time!
Another great tip that I use and I also heard by my MAC trainer is to always put your eyeliner on before you put on your lashes (or anyone elses.) There are a few reasons for this. First off, it will give you a general outline of where to place them. Secondly, it's much easier to fill in liner over the lashes than trying to place it on any glue that might have gotten on that area. The glue tends to grab more color in some areas making it look splotchy.
My favorite trick is to lay down whatever liner I'm using (I usally keep it a bit thinner when using lashes because they will thicken the look of your lash line on their own,) apply the lashes and then come in with Carbon on a 212 or 266 brush and go over the lash line, liner and glue with it using a pressing motion not a dragging motion. I think the powder eye shadow formula covers up any glue very easily and can get down in between the lashes. If you have accidentally gotten any glue anywhere on the lash, a little Carbon can be placed on it and it will hide it.
Okay, I didn't mean to write a novel about lashes but hopefully you find this useful!
