I have used RKT for sculpting in the past and there are a few tricks I've learned. I use the microwave method to make the RKT.......it's 100 times easier. Let the RKT mixtire cool enough to handle right in the bowl. Use gloves makes handling the RKT mixture easier.......lightly grease your gloves with Crisco and the mixture won't stick to the gloves. Do as much of your characters basic shape as you can and you won't have as much 'carving' to do. When you get your figure the shape you want, stick a few toothpicks or wooden skewers in it to aid you in applying buttercream frosting on it. You just want to lightly coat the figure with buttercream. Let dry, preferably overnight, then you're ready to apply fondant for the clothes and skin. I use a small artist brush to apply facial features using black food coloring for the 'paint'. For Mickey I would do oval fondant eyes and add the pupils in black food coloring. Good luck!!!
