This was a project I attempted without a commercial lamp shade mold. Instead, I took an old paper shade, filled it with styrofoam from a spray can, and build the shade on that. I learned alot from this project, like next time to use a commercial mold. And also, use smaller feather pieces so they will lay flatter to the mold. This version was 366 pieces.
I got the idea from a lamp I saw on the internet, but this design is my own.
