For lovers of butterflies, I will present here a unique shade that can easily be made up of cardboard.
Take one sheet of cardboard and cut it a rectangle whose size depends on the size of the shade you want to do. Using a pencil, draw a few butterflies on the cardboard (actually only draw their wings without the body) and cut them out with a knife. It remains tofold the cardboard in the shape of a cylinder and stick it with glue. When folding the cardboard wings of butterflies rise up, striving tomaintain a flat surface. Optionally, you can pre-painted cardboard in her favorite color.
