a lot of accidentals. how do I notate them?

[Sarah k Alawami]

Ok. I know how to notate the sharps and flats but I might have missed in the 
big manual how to notate naturals and there are a lot of them in this piece. 
For anyone familiar with the chopin prelude in c minor right hand and possibly 
left hand  there are a bunch of naturals. How do I notate them as when I hear 
it it will sound a mess. Here's what I have so far in the first violin part. I 
really hope all note durations are right. I know the rule about accidentals how 
it only as far as I recall effects the bar they are in unless otherwise notated 
but I'm so picky that I want to know they will be playing a natural in case 
they don't know the rule of accidentals. My instructed was not specific weather 
he wanted us to orchestrate for a amateur or pro orchestra so I'm just being 
over cautious.

I want to impress my instructor with out a headache lol! thank goodness for 
perfect pitch, except for today. lol!

I have some other questions but I'll address them in a new topic when I get 
there. right now I'm just worried about this top part as I will be playing 
those accidentals in the second violin and viola parts later.

Be blessed all and thanks for your help. I'm loving this lilly pond. Now let's 
hope I can grasp my head around this in time for the final project in may so I 
don't have to annoy everyone and I can focus on the music.
