The classic Stare, then comment trick.

If you like someone, try to notice something their wearing. Then every few minutes or so, stare at it. (please try to stay away from inappropriate areas when using this technique, lol). Eventually when the person see's you, say, "I was just looking at *article of clothing*." Then if you can, commplement them on it! It shows them your interested, and noticing them.
