You will need:
1. A pair of round Lennon style frames
2. Adhesive backed pearls and super glue
4. Time and patience - this is really laborious - only dare if you literally have nothing better to do
One by one, take a pearl in the tweezers, add a tiny bit of super glue to the back and place on the frame. Repeat this for the entirety of the frame and the arms of the glasses if you want to go BIG.
Et voila! The finished result...
