This cake was for an orthopedic surgeon that specializes in spines. There is a copper pipe that is supporting the spine and is attached through the cake board. The spine is 50/50 gumpaste-fondant and the cake is triple chocolate. One more lesson learned - make extra certain that your brushes are EXTREMELY clean before using again. I wanted to do a light bone-colored wash of foodcoloring over the bones so they weren't stark white... and the brush I chose had a tiny smidgeon of red left in it. Pink bones!
