I used a putty mold to create 12 replicas of keys out of clear plastic.  I made the keys translucent because I wanted them to be representations of keys, not the actual functioning key.  Hanging from the white branches, I wanted the keys to seem insubstantial, yet present, a representation.  To incorporate text, I wrote on the keys with sharpie, things that were important to me, or things I wanted to see.  Keys to….”the moon”, “happiness”, etc….
