Hi Sarah,

I have gone through the details regarding your poster.
But i don't know why, I am unable to open/save the file where you have specified the size.

Can you please clearly specify the size for the poster in inches or pixels?

36 X 48 X 3/16 in 

Thanks.

I can now open the image where the size is mentioned.
Its a three - fold poster, that you are looking for.

I will design a poster in a artwork size of 122cm width and 91.4 cm height.
I think that should be fine.
