If you have some old photo slides lying around then how about turning them to a lampshade?
To make this lampshade first you have to punch holes on all the four sides of each slide. Then if you want paint their sides with paint. Using split rings and pliers join the slides in rows. Then take a ring and attach the rows of slides to it using split rings. Then also link the rows to each other with split rings.
Fix the shade over your lamp and enjoy the view. With this lampshade not only you can have your lamp decorated but it will also take you to some sweet memories through the photo slides.
