I met this lady the other day at a grocery store. She's a full time cheese sculptor. She said three people in the United States make their living from carving cheese sculptures. She goes to various grocery stores and events and makes sculptures. She said that next month she's doing a life-sized Neil Armstrong cheese statue in honor of the moon landing anniversary. Because the moon is made out of cheese.
Her favorite medium is cheddar because it's a soft cheese that people will sometimes eat after the event.
Several of you have requested sculptures of my head. I think this would be a viable option.
