I've been doing the same eye make- up for 20 years - brown eyeshadow applied on one of those flat edged brushes underneath my lower lashes.
I fancy a change now so I've tried a couple of products and attempted to do some flicks but I ended up looking like a toddler drawing! 
So please let me know about any easier products to use or good tutorials because the vids I've watched on YouTube made me want to bite myself they were so full of waffle and unnecessary twattery.
I've tried the Avon gel pencil thing (the line seemed too fat) and also a (Revlon?) felt tip style pen (dragged my 40yr old eye skin).
I'd particularly like something less inclined to have smudged by the end of a night out.
