Cardboard Progress

So I"m trying to construct a seashell and my first attempt was a little too simple...

...just a bended piece of cardboard. Also, I didn't really know how to do the sides, but that didn't stop me from making a miserable attempt.

Then I decided to start over and cut out long strips instead of one long piece of cardboard for the top...

I'm going to fill out the top with more strips and hold it together with long strips in the back. Have no idea how this will look when I'm done but I really hope it will turn out great.
