I like the idea of having the letter E entangled in some type of material between to flat pieces of another material which I think would give it better shape and structure.
I think wire would be a good material to entangle the E in and possibly perspex for the top and the bottom. To see if this would work i made a small prototype using cheaper materials as perspex is quiet expensive.
I used acetate punched holes in it and then used black wire.
I like how this looks so now I am going to push the idea further and increase the scale.
