the spoon....she usually always loses the food and it ends up in her lap and she doesn't get enough into her
i used to make hunter's cereal etc more solid than usual when he started wanting to use a spoon so that it would be thick enuf to stick to the spoon and generally would hang on even if turned upside down, also used fromage frais instead of yoghurt for a while as it was thicker and stuck to the spoon. then after he was happily doing that i would 'help' him with the spoon and show him how to scoop it up and then helped him guide the spoon into his mouth the right way up, after a while he was fine on his own. use fav foods wherever you can as this really helped him catch on quickly.
the fork, i showed him how a couple of times and then would ask him if he could get a carrot/potato whatever on his fork. at first i found it worked better to just give him a couple of pieces on his tray to try and stab as the whole plate was a little overwhelming.
crayons, just a thought, hunter found them hard to start with until i switched to a different type of crayon. got the 'stubbie' crayons from Early Learning Centre, really soft so draw easily without needing as much pressure and are quite chubbie so he could get a good grip on them.
other than that, keep practising and really praise whenever she does use it
