Two notions for you to entertain: painting is adding; sculpting is subtracting.
Adding means bringing things together. Perhaps there’s a sense of starting from nothing.
Subtracting means revealing what’s already there. Starting from something.
Think about the edges of those notions. Think about adding being subtracting and vice versa. Think about sculpting as being painting. Combinations. Think about process and idea. Think about when you used to ride your bike without a destination.
