Here's Leslie Duff describing her work-
'This glass piece includes round bottle bottoms personally excavated from an old building foundation (unbeknown to me @ the time). Some of the glass is 100+ years old! Very interesting unique designs
So OF COURSE I saved them for "something"
And here is my something:
I built an 8x10 bathhouse ( a friend gave me a claw foot tub )
And of course you need to have a Bubble ( bath) window!
