I would consider myself a big flirt. I flirt with everyone, within reason, sometimes when I'm not even aware of it.
For me when you flirt, you're just signalling to people that you find them interesting, but you're holding back. Or, in the case of little animals, children and old people (all of whom I flirt with), just letting them know you think they're cute. Flirting is somewhere between sexual and innocent, and that makes it super-fun.
Any flirting tips? Not that I need any. 
Giggle
I consider flirting not only an art form, but an entertaining hobby~
I recommend making eye contact, then quickly lowering your eyes from his, as though in shyness. Then lift your eyes, meet his gaze again, and give him a sweet little smile.
I'm a huge flirt! I flirt with everyone (minus the elderly, children, and fluffy animals), and I don't realize I'm doing it most of the time. When I come off as very shy when people first
meet me, and it works to my advantage when I'm really flirting because I take control of the situation. It works great for me
For real flirting, like Curious Alice said, eye contact. Also, touching, and especially if you are somewhere loud, talk close to someones ear, and make sure they can feel your breath and maybe brush their ear with your lip.
Um, no real tips but I did have a shirt in high school that said "Flirt" in glitter writing. It was certainly a conversation starter.
I am smiley and friendly and ppl have always thought of me as a big flirt. Which I'm not. So I guess that a laid back attitude and a big smile do work

I suppose I'm a flirt in the sense that I'm really friendly and smiley. I get the girly giggles a lot too. But when it comes to someone I actually like I get a 'flirt block' and I go really
shy. 
I don't think I'm a big flirt but other people tell me differently. I'm another one of those never realizes your flirting until someone points it out to you. But that usually ends up in my favor.. but as for tips u kno stuff like holding someones passing glance a lil longer than the normal courtesy glance. lol i love to play with straws and whatnot too i'm jus silly tho, and that usually works for me too
I've always been told I'm a flirt. I definitely don't do it on purpose, but I have become more conscious of it. The thing for me is that I'm always smiling and giggling (for real). I have
also realized that I unconsciously (more consciously now) do that eye contact thing CuriousAlice mentioned.
It's definitely fun and extremely friendly. Go flirts!
Haha i've always been described as a flirt too...I've toned down recently thanks to finding a wonderful man. BUT when I did flirt for sport and fun I always did the eye contact as Alice said. and casual touching of the arm...laughing, just having fun!!

I think being coy is the name of the game. Make them want more from you.

hello people. HELP HELP!! i need some advice. so i now this guy who i am head over heals for. i want to flirt with him but i have a hard time trying not to wear my feelings on my sleeves. i mean i want him to know that he has my heart. i want to play hard to get so i can see if he feels the same way. i've known him for most of my life but i've never had the guts to bluntly express my feelings. so please give me some advice in flirting so i can find out if he feels the same way about me!!
Kalikaboki,
Okay so you really like this guy? You said you have known him for most of your life so you must be pretty comfortable around him, right? So the problem is you want to show your feelings, but
not too strongly but you also want to play hard to get. Being subtle is definitely the key. I mean, be your normal self, just jazz it up a little, you know? Compliment him, do something a
little out of the ordinary that he wouldn't expect. Like when you normally say hello to each other or comment on something he says, touch his shoulder or shyly joke around with him.
Definitely the whole eye gaze thing that Curious Alice mentioned. That lets him know you are interested.
flirting's as simple as turning everything they say around on them and making them smile at your deliberate misunderstandings. Flash them a smile, and they're hooked.
I sometimes accidentally flirt with guys, but I don't think it's fair to
them if I play games. Talking to guys is easy for me since I like most of the same things they do, and guess what? Being nice and being real has gotten me more attention from more awesome
guys than playing manipulative games ever did.
I couldn't express the eye thing better than curious alice. Isn't it weird how that is hardwired into us women? (sorry ever the scientist, me...)
One of my best ways to go. Talk to the guy, be half mysterious half easy-going, show who you really are, he will embrace it in anytime BUT! make sure you have the right guy to flirt with
Now this aint much of a good tip but it works for me ^_'
Ive always been accused of being a flirt but I dont realize Im doing it. Then when Im purposely flirt Im way to obvious
I just cant win
