The key to great eye makeup is to blend, blend, blend. Then when you think you’re done, go back and blend some more. Blending is a broad term though, I remember when I was a novice I was so confused by what this actually meant. Basically it starts with a good blending brush. Something like the #217 brush from MAC. It’s dome shaped so you pick the product up with the tip of your brush and the shorter bristles around the tip do all the work for you. To take it a step further, and this is the important part of getting a professional look, with a clean brush blend the edges of where your eye shadow ended. This will make it seem as though the color fades out, rather than there being a definite line where it stops.
