I've mentioned many times recently that I have been using MAC's Sable eyeshadow non-stop, and another product that's been getting a lot of love from me is the Urban Decay 24/7 Glide-On Eye Pencil in Corrupt:
This is a dark brown liner that has tiny bits of sparkle in it. The sparkle is subtle enough that you can wear this during the daytime, as I have been recently (often times with Sable). I like this shade because it is darker than UD's Bourbon, but not as harsh as black liner.

Here is a quick look I recently wore with MAC's Orb shadow on the lid and Wedge shadow in the crease.
Isn't brown liner lovely? I even lined the lower lashline....just halfway, not the full lashline...to give some emphasis to the bottom lid without closing in the eye too much. What do you think?
