PIPE icing along long edges of 3 of the crackers; press edges together to form triangular box. Let dry.
CUT 2 of the crackers into triangles to cover ends of triangular box using serrated knife. Carefully pierce a hole, about 1/8 inch in diameter in center of each triangle with straight pin.
FOLD the 18-inch piece of green curling ribbon in half. Thread folded end through hole of 1 of the triangles, pulling about 5 inches of ribbon through cracker. Continue threading folded end through triangular box, then through hole in second triangle, pulling through 3-inch loop to make hanger.
ATTACH triangle with the loop end to triangular box with icing. Pull ribbon through second triangle until triangle is against the triangle box; attach with icing. (If ornament doesn't hang straight, pack box with tissue to balance.)
THREAD candy on ribbon on bottom of box; tie knot on end to keep candy in place. Use scissors to curl ribbon. Pipe icing along all edges of ornament; dip in colored sugar. Let dry.
