practice, thin paint, small pointy brush...
Also what helps with avoiding the wishy-washy indistinct look is to paint the design in a darker colour first then do finer lines inside that so you have a little dark border. Even if you don\'t have border showing it still helps. Practice that one with wider borders first then try to make your lines thinner as you get the hang of it. Eg you could start with a simple wide line border for a robe to get used to the way of it.
Highlight it in line with what you\'re painting over, and also if it\'s big give it some of it\'s own highlighting too. I can\'t remember who said it, but it was someone on here who pointed that out. Eg big thing on a cloak: highlight the pattern so that it\'s lighter at the top, but also highlight it with the folds of the cloth. Makes it look more like part of what it\'s on.
oh, one more thing - make sure there\'s not too much paint in your brush, or you won\'t have any control over where it goes. You could wick out the excess by touching it to a damp paper towel - I tend to streak it over my thumb/thumbnail a couple of times to get it right. With a really tiny brush like a 000 you might find that the paint dries a bit in the tip before you\'re done, also messing with control. Happens to me all the time as I paint quite close to the lamp - just dip the tip in your water, in the paint again, wick excess out and go again. After a couple of times theres generally enough paint in the brush to keep going for a while. Erm - that\'s probably really bad for the brush but I do it anyway

. I try and clean them fairly regularly with brush soap so maybe it\'s not too bad. It always gets up in the ferrule when I\'m blacklining or painting designs.
sorry if that\'s all a bit obvious, I\'m tired and rambling now... and it\'s only 10pm, I\'m so old :-/
