well i wear black eyeliner like everyday for the whole day..
but after like and hour or so my eyeliner which before
looked smooth, looks all crumbly.
does this happen with all eyeliner?
or is it just the eyeliner i use?
is there and eyeliner that doesn't go all crumbly?

oh.. and i don't like pencil eyeliner.

i use a liquid liner. but another way that i do liner is by using eyeshadow. it doesnt come off as easily. so you could try using a black eyeshadow and dotting it under your eyelashes and then use the stick thing and smudge it into a fine line into your eyelashes.

yeah thats a good idea.
i'm scared of liquid eyeliner.. cause once my friend leaked it in her eye
by accidently, and her eye turned black.. for a day or so.

Eh, so I guess you use liquid liner then?
Not my favorite to use, it def gets crumbly and wears off weird after a few hours.
Pencils are better, but you don't like those.

I suggest finding an eye shadow that matches close to your eyeliner. (I assume you use black, go find a black eyeshadow)
Then using an eye makeup brush with a small tapered end, you dip the brush in the eye shadow and use it as you would an eyeliner.

It stays on all day [I do it all the time], it doesn't crumble either, and it gives such a nicer smoother look at the end, also, it's easy to blend it into your lashes, so the makeup looks more natural. [Another plus, you can always play up the 'smokey eye' effect as well].

What I usually do is take an eye pencil in black and quickly line my inner low rims of my eyes, and just put a base line on the top, then sweep over it with the black eyeshadow with the eye makeup brush to make it look better and stay on longer. It just looks a whole lot better, trust me.

oh yeah, and i forgot to say that i saw on tv once that you can use mascara and like.. do it closer to your skin so then the mascara will LOOK like eyeliner. but i've never tried it....

I use pencil eyeliner on the bottom and liquid on the top.
The eyeshadow thing does help.

PENCIL PERFECT by L'oreal is great

I have a not quite pencil and not quite liquid. it works very well

Messing around with products can help.

yeah thats what i have.. but it gets all crumbly

Actually, there's loose-powder eyeshadow that I use. There are brushes available that are strictly designed for it, too:

same here, but use liquid eyeliner.. it might be hard to get it off at night but it doesn't go away or crumple like the pencil ones..

I like the pencil eyeliner better.
