Textiles GCSE help!!?

Well I'm trying to design a wall hanging which is based on the theme of 'buildings around the world', and I've decided to do the Eiffel tower as my final design, however, I'm having trouble with the wall hanging shape, according to my teacher, it needs to be imaginative and not boring, however, I cant think of a shape which will be easy to fit in the elongated shape of the Eiffel tower in, the only imaginative shape I can think of is a triangular shape, but i really need some other ideas to help me :/ any help is much appreciated!
