After uncovering the original painted on medallion on the ceiling, we had been throwing around ideas of what we could do to incorporate some sort of new design into the new ceiling that would pay homage to it. We made many trips to the local home improvement stores and found a few different bits that we figured we could put together to create a new ceiling that would look like it was original to the house. Instead of a circle, we decided to go with an ellipse that would accentuate the shape of the room. Here, I’m using a little geometry, a string, and a pencil to create the outline of the ellipse.
