Hi! I am making an edible map of Georgia with my students. It will highlight the 5 main regions of georgia and the 7 major rivers. I have most of the map figured out but need help with 1 region. For the rivers we will use blue sour punch straws. Coastal Plains- green frosting Piedmont- M&M's Blue Ridge Mts- Chocolate chips Appliachian Plateau- Rolos But the Valley and Ridge stumps me. It needs to be edible. Please help. Thanks.
