Best way to draw border around sprite

[SteppingRazor]

Hello guys,

What I wanted to do is when the user hovers the mouse over the sprite then the game will display border around it. I've created two sprites one is a normal sprite and the second one is just a border. At the beginning I put both sprites on the same position and I hide the second sprite. When the user hovers mouse over I set visible property of the second sprite to true, on hover out I set it to false. Simple and it works. But I was wondering is there a way to achieve this without adding second sprite?
