Chalkboard for Teacher

This was for my daughter's teacher to give our appreciation for being such a wonderful teacher. BC covered in MMF with MMF details. Apple is also cake. I had so much trouble with my red fondant losing its elasticity from adding too much red color. I colored my MMF the day before to let it get darker but I still had to add so much red color. Anyone have any suggestion as to what I can add to bring back the elasticity? TIA
