Hi, what you say if I offer an idea of lamp-bracket from pens. Manufacturers are producing a lot of pens sizes, colors and shapes you want. So I propose don't throw pens away when ink is over. Transparent and light colors of pen body will give the best fit because it let pass the light through.

Just fix pen bodies together with sewing or decorative tissues in the manner you like and you will find your room in a new way of style. That's simple to do and no need much brain.
