I made the small scale swan and am now on a mission, creating a HUGEEE one, using A4 paper for each individual triangle. I did the maths (probably wrong, maths isn't my forte) but I aim to make around 2020 triangles, which would give me enough for the body, both wings and the neck. It sounds like a lot but i have about four weeks and if i do about 8 a day i should be okay :)
I've currently done 270 and will probably have done 300 later on.
