Time to ease back into some quilting stuff. These are little refrigerator magnets. My grand daughter carved these when she was eleven years old. These were her very first carvings. The penny in the photo shows the size of the squares. This type of carving is called relief carving. The carved "grooves" are done with a small "V" shaped gouge. The incised lines that the "V" tool makes also serve as a "stop" between the painted colors, to prevent them from "bleeding" into the next color.
People often ask when is a kid old enough to begin to carve wood. Generally, ten to twelve seems to be a good age to begin well supervised carving.
