This is a simple and effective way to tart-up an inexpensive paper lampshade using office supplies.
Decorative paper clips (I found these circle paper clips at Target; 50 for $2.99.)
Small paper punch (Or anything pointy will do.)
Mark shade with pencil at uniform intervals. I spaced my markings 1 inch apart.
Punch holes at markings.
Slip paper clips into holes.
For another office supply alternative, how about using key tags with metal rings instead of paper clips? And for a non-office supply approach, try using dangling earrings or tiny Christmas balls.
